It’s never is ok to have a brain fog slowly lift and realize you are bleeding all over yourself. It’s a calm moment when you are in that state where it takes another five seconds to realize what just happened. No pain, no panic, but no understanding. Just observation. “Something just happened. I’m bleeding. What happened? Where am I?” followed by “Oh shit I just had a nasty bike crash.” A terminator style system check begins to ascertain damage when all hell breaks loose.

In my case it was a very controlled chaos. One of our guides – Marko – was whatever the Czech version of an EMT is. By the time I realized who I was and where I was, he was in my face, telling me not to move, stabilizing my head as he directed someone else to untangle the bikes from me. As the fog lifted, I felt ok, could talk, and he realized my jaw wasn’t broken. He commanded me not to move yet as he emptied his emergency kit. He looked in my eyes and made sure they responded. He asked me a few questions which I presume I answered correctly. He made me move my jaw around more. He did a scan of the rest of my body, especially my legs, and then started taping up my still bleeding chin.

By this point the fog had completely cleared and I knew what had happened. I was on vacation for a week in Slovenia celebrating my partner Seth’s 40th birthday. Seth is a huge cyclist so his wife Greeley gave him a wonderful present of a week bike trip with seven of his cycling buddies and his three partners. We were on day four of an outstanding life experience together.

Until this summer I hadn’t ridden a bike since I was in high school other than a few random times on vacations. I’d never done any serious cycling and had completely missed the cycling craze of the last decade. Six months ago Seth helped me buy a bike – I’ve been mixing it in all summer with my marathon training, discovered Strava, learned how to shift gears properly, had started to learn what gear I should be in, experienced several back to back 30 mile training rides, and started to learn about how doping worked since that seems to be the central theme of many cycling conversations right after detailed descriptions of accidents.

The rides in Slovenia were awesome. The first day was 70 km – mostly flat. I took the second day off and then had another great 70 km day – by this point I was in a groove. On day 4 we had a huge 20km 2500 climb and descent, so I decided to run the hill which ended up being just about a half marathon. I started before the cyclists and finished 15 minutes before they did.

The first crash happened about 1 km from where I was waiting. Seth got a flat tire on a steep downhill and bit it immediately. He was ok beyond bruised hip and severe road rash – he shook it off and at this point I rejoined the group and got on my bike. I started off tentatively and was in the back of the pack as everyone else took off.

In hindsight there was no way I should have gotten on the bike. The next 1.5 km was a steep downhill and as I picked up speed to 40 km / hour I thought to myself something like “wheee this is fun” as I caught up with everyone in front of me. I then noticed a bridge coming up that corresponded with a sharp left turn. At this point, I have very little recollection of what happened. I’m sure I started braking but I knew I was going too fast. My partner Ryan was directly in front of me and I was coming up on him fast – I remember him saying, in a very calm, rational voice, “what are you doing?” The next thing I remember was blood dripping from my chin.

Those that observed what happened tell me that Ryan let out a blood curdling scream, I crashed into him as I was trying to make the turn, my bike got tangled up in his, and I went over the handlebars. The visor on my bike helmet was broken, so I clearly landed on my head – probably first since my chin only needed four stitches and my jaw wasn’t broken, although a molar was.

Thankfully Ryan was fine. He broke my fall and ended up with a few scrapes but other than being shaken up by his partner attempting to mate bicycles, he was ok. I had a daydream the next day about the two of us going over the side of the bridge tangled up together which just reinforced how glad I was that I hadn’t caused him to be injured.

Marko and Ron – the leader of our tour were awesome. Marko got me cleaned up and Ron tossed me in the van and took me to a local clinic in the next town (we were several hours away from a major hospital.) The doctor saw me in 30 minutes and stitched up my face in five, charged me 52 euros, and sent us on our way. We went to our hotel where I found out there was a dentist who had an office behind the hotel. Remember – this is a tiny little town in Slovenia (Kobarid). The dentist was amazing – he had better equipment than I’ve ever seen in the US, used a laser scanner to reconstruct my tooth, printed a new tooth on a milling machine in a back room, and within an hour sent me on my way with a new tooth for a mere 250 euros. From now on, I’m doing all my elective dental work in Kobarid.

All of that was on Thursday. I’m back in NY where Amy and I are planted for the next ten days. Other than stitches, a pair of nasty road rash cuts, and bruised ribs, I’m fine. I’ll be back on the bike again – I was having a lot of fun until suddenly I wasn’t, but the memory of that moment will fade with the scars. I guess I’ll be growing that beard I’ve been avoiding for a while.

I was going to write something about a new book I’ve just published but I woke up this morning and that felt trivial so I’m going to save it for next week. Instead, I’m going to talk about my day yesterday.

My long time friend (dating back to the mid-1990′s) Andy Sack has testicular cancer. Before I get into things, he’s in the middle of chemo, has a 95%+ cure rate, is open and public about what he’s going through, and has an incredibly positive attitude.

I’ve tried to call or write Andy every day since his diagnosis. I’ve probably done it 80% of the time (I know I’ve missed a few days.) Every day at 5pm my iPhone gives me a reminder to “call Andy Sack.” Most of the time I get his voice mail and leave a message, other times we talk for a few minutes. While I was off the grid last week in Hawaii I sent him a postcard every day. Either way, I get a chance to tell him that I’m thinking of him and give him some additional energy from out in the universe, wherever I am. But this was the first time I’ve been able to get to Seattle to spend time with him.

I took the early flight from Denver to Seattle and we met up at the Kinect Accelerator where the program has just started. We found a room to just sit and talk for about 45 minutes. After a hug and a heart felt welcome, we started talking about how things were going. Our first 15 minutes were filled with lots of tears and emotion as I gave Andy a gift from a few of his friends including me and Amy and we connected physically for the first time since he was diagnosed.

I was curious about the experience he was having and he was very open about chemo, how it impacted him, and what the process was. We talked some about the dynamic of a loved one being sick or hurt since Amy’s had a broken arm for the past few weeks. While the broken arm isn’t in the same category as cancer, it has changed the way I’ve thought about caregiving as it’s the first time I’ve had to be – in Amy’s words “her man servant” – in our relationship. Amy called during this time and when the Imperial March (Amy’s personal ringtone) started playing on my iPhone Andy laughed a good belly laugh. I put Amy on speaker, the three of us had a nice talk, and then we wrapped up and had a TechStars related meeting.

We went to lunch with David Cohen, the CEO of TechStars. We talked about work, but we also talked about life. Andy was total present – he was having a good day physically and emotionally – and it was great to be around. After lunch David got in an Uber and headed to the airport to go back to Boulder; Andy and I walked around the corner to his office and BigDoor’s office (he’s on the board of BigDoor with me, their office is on the first floor, his is on the second.) I said hello to the BigDoor folks, hung out for a while and caught up on email while Andy had a meeting upstairs, and then he drove me to my hotel and we said goodbye for the day.

I had a few more meetings and then ended back up at the Kinect Accelerator for the Mentor Mixer. The program started on Monday and this was the first meeting of all the mentors. I gave a talk about how to be an effective mentor during the introduction to the program and afterward noticed Andy in the back of the room. This was a nice surprise as I didn’t expect to see him again on this trip. We hung out at the mixer a little and then took off to go have another meal together – this time alone.  We talked about a few experiences in the distant past and I vividly remembered a dinner in Brookline in the 1990′s with Andy, Alexa (his wife), and Amy. I couldn’t remember the restaurant, but I had the visualization of the entire experience in my head and shared it with him (he remembered it also). We talked more about a wide range of things – some business, some personal – and just enjoyed being together.

I got more than my fair share of his time yesterday. And it was awesome. As I was laying bed at 11pm drifting off to sleep I thought of him some more, some of the ups and downs we’d had together, and how much I treasured him as a friend.

We’ve been through lots of things together. One of the first things he said to me when he saw me was “your support of me through this period eliminated any fears I had lingering about our relationship in the context of any money that I’ve lost for you.” I’ve invested in a number of things that Andy has done dating back to his first company (Abuzz, which was a success and acquired by the NY Times for about a 4.5x of my investment.) But we’ve also had lots of things not work (Bodyshop.com – 0.5x, Judy’s Book – 0.25x.) However, I never, ever have worried about it – my willingness to keep trying and working with great people trumps the specific returns of any individual transaction. And more importantly, my personal friendship and loyalty is built on trust and a long term arc of honesty, not transactional results. While we’ve both screwed up plenty of things along the way and had our share of disagreements, we always resolve them and move forward. I’ve told Andy this several times in the past, but when you face mortality you have a chance to really understand (and express) this.

I wore my Fuck Cancer shirt all day. Several people gave me positive comments on it and one stood out. Near the end of the day, a woman who I didn’t know said “great shirt.” She looked at me with acknowledgement and a real spark of connection occurred. I realized, at that moment, that cancer is a disease that defines many people at a profoundly deep level, especially when they survive it.

On Saturday I’m running a 50 mile race in Sacramento. I’ve been thinking about this all week as I try to get my mind into it. It’s been hard to get real focus on it because I’ve had a busy week and I know that Friday will be my transition day. But as I sit here, the 50 mile run doesn’t seem that hard. Sure – it’ll be a physical and emotional challenge, but it’s not surgery, a 64 day chemo regimen, and the emotional challenge of “beating cancer.”

Life is short. And uncertain. Live it every moment. Andy – thanks for being you and letting me be part of your life.

My dad is one of my best friends. His birthday is on Saint Patrick’s Day and it has been a bright green celebration for as long as I can remember. He turned 74 today and we had dinner tonight at Oak at Fourteenth with Amy, my mom Cecelia, my sister-in-law Laura, my brother Daniel, and their daughter Sabrina. We had a wonderful evening and it reminded me once again of the importance and delight of family.

I’ve learned many things from my dad during the 46 years I’ve been on this planet. Following are a few pivotal ones that have shaped my life.

Age 10: I told my dad I didn’t want to be a doctor like him. I didn’t like how hospitals smelled, I was bored when we did rounds together (I just wanted to sit in the corner and read), and I didn’t like being around sick people. He told me that I could do anything I wanted to do.

Age 12: I hated learning Hebrew and thought being Bar Mitzvah’ed was stupid. My dad didn’t fight me on how I felt, but he told me tradition was important and this was a seminal jewish tradition. I procrastinated as long as I could and then crammed over the last few weeks. He sat with me, coached me through it, and was patient with me when I continued to fight the process. My Bar Mitzvah was a powerful learning experience, and, while I eventually became an atheist, am glad that I participated in the key jewish tradition.

Age 17: After two months at MIT, I was ready to quit. All of my friends had gone to UT Austin, including my girlfriend, and I was homesick and lonely. As we wandered around Concord, MA on a beautiful October day, he told me to give it a year and if I still didn’t like it, I could go somewhere else. But he told me I’d be short changing myself if I didn’t give it a year. By spring time I had fully embraced MIT and never looked back.

Age 21: Dave Jilk (another Saint Patrick’s baby) and I started Feld Technologies. My dad was our third partner, sat on our board, and contributed continuously as a mentor to us as we figured out how to create and build a company. He personally guaranteed a $20,000 line of credit with his bank which was our beginning working capital (which we stupidly used up immediately, although that made us realize we had to be profitable and cash flow positive from the beginning because there was no more money to tap.) Almost every year Dave, my dad, and I would go away somewhere for an annual meeting. I remember these weekends fondly as they shaped the path of our business. My favorite line from this period that I remember from him was “if you aren’t on the edge you are taking up too much space.”

Age 24: My father resisted the easy temptation to say “I told you so” when I got divorced. When I dropped out of a PhD program, he told me he supported any decision I made. When I was feeling sorry for myself, he’d remind me cheerfully that “everyone pees in the shower.” His unambiguous support of me, at a period of darkness in my life, was priceless.

Age 29: When Amy and I decided to move to Boulder, the first words out of my dad’s mouth were “that’s a great idea.”

There are many more like this, but this should give you the sense for it. In addition to being one of my best friends, he’s been an incredible mentor, business partner, and supporter. I love his sense of humor, his joie de vivre, and his endless curiosity. He always lights up any room he’s in, is always learning, and keeps on trying new things.

Dad – happy birthday. You are awesome. Green suits you.

I’ve been obsessively tracking data about myself since 2009. The most visible data I track is on Daytum which includes Miles Run (by location), Books Read (by type), Airplane Flights (by carrier), and Nights In Town (by city). I also track all of my running data (most recently on RunKeeper and SmashRun) and all of my health data (including what I eat) on Fitbit. I track plenty of other stuff, but those are the public / systematic things.

I started doing this in 2009 – see My 2009 By The Numbers for how I was thinking about things then. This year I’m thinking about things more categorically, based on a set of activities I do that drive what I spend my time on. Here’s where the year ended up.

Running: I had a great running year – probably the best in a long time. I ran six marathons, including four in eight weeks, and the last one of the year was the fastest since 2003 in 4:28:46. Overall, I covered 1,125.91 miles (not including the 6.5 miles I’m going to run today). 339 were in Boulder; next best was a monster month in Tuscany of 156.97 miles. I crossed 100 in Keystone and had another strong month in Paris at 94.65 miles. You can tell that I had two weeks of vacation in Tucson this year, plenty of short runs in cities I traveled to for work (SF, NY, Seattle), and then a bunch of marathons.

Weight: I started the year at 208, hit a high point of 219.4 at the end of October, and weighed in at 202.8 this morning. My goal is to be 190 on 12/31/12.

Sleep: I clearly missed a few days since I only have 354 days reported for this year. I often get asked how often I travel vs. sleep at home. Eldorado Springs is where I call home so I was there 99 nights. Boulder, which is a condo I have down the block from my office logged 40 nights. So – for the year, I was in Boulder for 139 of 354 nights, or 39% of the time. Keystone was very light this year – we were only there 25 nights (and 14 of them were the past two weeks). You can see my month in Tuscany in August and month in Paris in July, two weeks of vacation plus a little in Tucson (I guess I like Tucson), 16 nights in New York, 10 nights in San Francisco, and 10 nights in Seattle. I was only in Boston five nights this year – that will change in 2012 as I’m spending the second half of January there. While I swore off red eyes several years ago, I still ended up doing three of them this year. And if you are curious about the other 16 places, they are Los Angeles, Newport, San Antonio, Napa, Boise, Ann Arbor, Bismarck, San Diego, Orlando, Kansas City, New Orleans, Washington DC, Montreal, Portland, and Colorado Springs.

Reading: I didn’t read that much this year – only 41 books. In contrast in 2010 I read 52 books and in 2009 I read 78. Business, Biography, and Mental Floss were all even at 7 and then Philosophy, Fiction, and Sports at 4 each. I’ll definitely read more in 2012 and as you’ve probably noticed I’ll continuing blogging my reviews.

As a special bonus, I’m about to cross 6,000,000 steps logged on my Fitbit. That’ll happen today on my run. I wonder if I’ll get a badge for that.

When I reflect on 2011, I had a great year on many fronts, both personal and professional. I’m looking forward to 2012 and am doubling down on my personal commitment to myself to focus on things that matter and ignore the noise.

Today is my 46th birthday. I’m hanging out with a bunch of friends and family, enjoying their company, and reflecting on the past year. 45 was a good, but intense year. Lots of ups, a few downs, and much learned. Following are some of the things I’m chewing on as I start being 46.

Mortality: I’ve had a lot of reminders of mortality lately. In the past year, several close friends’ parents have died and a few other friends have gotten very ill. When I think about being 46, I accept that even in the best case scenario I’m probably half way done with my time on this planet. I’m happy with my physical self – I’m probably in the best shape I’ve been in since I was in my early 20′s – but I’ve finally decided to really focus on dropping the 20 pounds I want to get rid of. Rather than being 210, I’d like to spend the rest of my life around 190.

Optimism: I’m an optimistic person – always have been. I’ve noticed an incredible amount of negativity around the system in the past year. Historically I’ve tuned out most of it because I ignore all non-tech news, but I’ve really noticed it in the tech news the past year. Clearly a switch flipped and the journalist / bloggers decided the best way to get attention – or at least links – was to be negative. Balanced is fine (not all is good), but the preponderance of negative trending toward nasty and hostile, especially without any facts or substance behind it, is a drag. I haven’t decided what to do about this yet, but I think I’ll likely just keep tuning it out the best I can.

Learning: I had another awesome year on this front. Between the companies and entrepreneurs I get to work with, TechStars, the books I’ve written, my running, and all the random stuff that I talk about and explore with Amy, I’ve learned more than I could have hoped for. I especially loved the experience of living in a new city for a month (Paris) – just living – not trying to be a tourist, or alter my normal work rhythm, but live in a totally different place for 30 days. Amy and I are going to do this in New York from mid-April to mid-May in 2012 as part of our “live for a month in a different city every year” experience.

No Assholes: I’ve worked really hard to get to a place where I get to spend almost all of my time with people who I want to spend time with. I’ve been able to do this while figuring out how to engage with lots of new, interesting people all the time. I’m going to work even harder at this at 46 – more great people, no assholes.

Travel: My greatest personal disappointment while I was 45 is that I sucked at managing my travel – again. At several points throughout the year I was completely exhausted from the endless cross-country travel. I’m taking a totally different approach at 46 – I’ve already locked down my entire schedule for 2012. With the exceptions of emergencies, I’m not making any trips that aren’t already scheduled. There will be a lot more video conferencing in 2012 and longer stays in cities when I do travel. Who knows if that tempo will work better, but I’m going to try.

For all of you who are part of my life directly, who know me through this blog, or have a relationship with me in any way, thanks for being part of my first 45 years. I look forward to spending time with you during the next 45.
