I’m in Las Vegas at CES. I walked the floor yesterday, had a bunch of meetings in the afternoon, and then went out to dinner at Nobu with my partners and a bunch of the founders of companies we are investors in. It was a great day but at the end of it I was totally used up, especially since I got up at 4am Las Vegas time to go to the airport.

My plan today was to walk the floor of CES some more. I only have one thing scheduled at 2pm (a call with Mark Udall, one of our Colorado Senators, about PIPA) – the rest was left open. But yesterday I felt like I saw everything I wanted to see. And I was tired of bumping into people, overwhelmed by the smoke everywhere, and way over stimulated. On top of this, I’ve been feeling a little flat (not depressed – but down / off balance) since the middle of last week, I’m on the road through the end of the month on the east coast, and I’ve got a head cold that I’m having trouble shaking.

When I woke up at 6:50am this morning, I decided I was going to camp in my room today. Just me, my computer, and whatever is on the other end of my computer. We’ve got another Foundry Group event tonight – by then I’ll probably feel like seeing humans again. But until then, I just feel like hiding for the day. The one exception is a run, which my body is begging me to do, even though I have snot dripping out of my nose.

Some days it’s best to just hide in your room. Today is one of those days for me.

My twitter stream this morning had a conversation between Kara Swisher and Chris Sacca about a TED video from Jill Bolte Taylor. Kara recently had a TIA (minor stroke) and wrote about it. The conversation between them prompted me to watch the TED Talk by Jill Bolte Taylor about a massive stroke that she’d had. Taylor is a brain scientist, which makes the whole discussion even more incredible as she had a chance to study and think about her own experience of having a stroke.

I strongly encourage you to invest 18 minutes of your life in this. It’ll change how you think about your brain, as well as possibly a few other things.

I’m off to run the Zeitgesit Half Marathon in Boise, Idaho with my friends Mark and Pam Solon. It’s another beautiful day on planet earth.

I am completely wiped out. It’s noon on Saturday in Colorado. I just had five days in a row of 18 hour days. I started the week in San Francisco and flew back home on Friday night from New York (with a red eye in between). It was awesome, but exhausting.

In addition to all the work, there was plenty of ambient emotion last week including some around mortality (Steve Jobs died and a close friend’s father died). In between everything, I spent a had a lot of meals with people I haven’t seen in a while, or whom I’m really close to. On top of that, there were hundreds of emails a day, plenty of telephone calls, and lots of random stuff to deal with. And plenty of running, coming off a weekend of back to back long runs (14 miles on Saturday, 16 miles on Sunday). And the Imperial March rang on my phone several times a day when Amy called, which always gave me a nice positive emotional charge.

I slept 12 hours last night. Amy made me a great breakfast and I’ve spent an hour catching up on unread emails from yesterday. But I’m just fried. And I’m going to crawl back into bed for a nap, go to a movie this afternoon, and then have a quiet dinner with Amy somewhere.

When I reflect on last week, I consciously spent very little time thinking deeply about anything. My runs were mostly mental garbage collection times, I slept on the airplanes, and I was in the moment the rest of the time dealing with the present. Sure, some of the discussions were longer term, strategic type things, but all the thought processes were surface level vs. deep discovery.

I’m working on a book called Entrepreneurial Communities. It’ll be done by the end of the year. I’ll likely self-publish this one as I don’t perceive any benefit to having a publisher now that I’ve done two books the traditional way. I also don’t want to introduce an additional six months into the writing to publishing cycle. I spent exactly zero time working on the book last week, although I had no expectation that I would.

But when I think about what I learned this week, and what I talked about, plenty of it pertained to the book. While I consciously spent very little time thinking about entrepreneurial communities, I unconsciously spent a lot of time thinking about it. And while my surface level discussions about longer term things didn’t impress me as deep thinking, by talking out loud about complicated issues I continued to modify the way I talk and think about them.

This is a style of mine. While I don’t “think out loud” like some do, I “refine my thought process” by talking about – and doing – things around the topics that I think deeply about. The development, creation, and sustaining of entrepreneurial communities is one of those topics that I’ve been doing a lot of thinking about lately, and anyone who knows what I spent my time on knows that many of the things I work on pertain directly to the activities around these, rather than just the thoughts around these.

By being insanely busy in areas that I think (and care) deeply about, I’m actually engaged in an “active deep thinking” rather than a passive deep thinking. It’s easy to end a week like the last one (which is a pretty typical week for me) with the reaction of “wow – that was intense and insane, but I didn’t really have any time to think about what I wanted to think about.” That’s wrong – I spent the entire week actively thinking, which makes my ability to deeply think about topics I care about even more powerful and effective.

I’m sure there is some philosophy, or psychology, about how a human links passive and active around the formation of thoughts, ideas, and theories. I’m not going to think deeply about that, especially since it’s meta in the context of this post, but I’m certain that the answer the my question that I posed in the title is a resounding yes when you combine active and passive thinking.

I go off the grid four times a year for a week at a time. During these weeks I put up a vacation reminder that says I’m off the grid, not checking email or phone, but if it’s an emergency I can be found by my assistant Kelly. While I leave her email and phone info in the vacation responder text, she still checks my email to make sure that nothing critical is going on. While this works well, Josh Kopelman blew my mind with his awesome vacation responder a few weeks ago.

I am currently out of the office on vacation.

I know I’m supposed to say that I’ll have limited access to email and won’t be able to respond until I return — but that’s not true. My blackberry will be with me and I can respond if I need to. And I recognize that I’ll probably need to interrupt my vacation from time to time to deal with something urgent.

That said, I promised my wife that I am going to try to disconnect, get away and enjoy our vacation as much as possible. So, I’m going to experiment with something new. I’m going to leave the decision in your hands:

• If your email truly is urgent and you need a response while I’m on vacation, please resend it to interruptyourvacation@firstround.com and I’ll try to respond to it promptly.
• If you think someone else at First Round Capital might be able to help you, feel free to email my assistant, Fiona (fiona@firstround.com) and she’ll try to point you in the right direction.

· Otherwise, I’ll respond when I return…

Warm regards,
Josh

From now on, I’m going to set up an account at interruptyourvacation@foundrygroup.com and leave this in your hands. Powerful – and fucking brilliant.

Congrats and good karma to my friend Bre Pettis on being able to take his new child - Nika – home from the NICU.

Over the last few months as we were working together to close the MakerBot financing, Bre and his partner Kio Stark had Nika prematurely, which resulted in a bonus six week stay in the NICU. I talked to Bre a number of times during this period, often when he was camped out at the NICU, and he was remarkably calm and engaged during this period.

He’s written a very detailed, thoughtful, and intense post about how to survive the NICU. While I don’t have any kids, nor do Amy and I plan to, I expect all of my obsessive behavior would come out with a vengeance if I ever ended up in a similar situation to Bre’s. My guess is that his rules apply to the hospital stay of any loved one and are well worth reading.

Bre – thanks for taking the time to write up your survival guide. I’m glad everyone is home, safe, and healthy.

Rosabeth Moss Kanter has an excellent post up on the HBR Blog titled Should Leaders Go on Vacation? Recently, I’ve seen plenty of commentary in the popular press (especially Fox News articles) about the inappropriateness of leaders taking vacation. Kanter does a nice job of dissecting the dynamics around leaders going on vacation and suggests the leader address five questions in the context of the vacation.

• What is the vacation narrative?
• What is the vacation timing?
• What is the rest of the team doing?
• Are there continuity, backup, and contingency plans?
• What is the vacation symbolism?

I’m a huge believer in the importance of vacations for leaders, entrepreneurs, and everyone else. I work extremely hard – usually 70+ hours a week. This is simply not sustainable, at least for me at age 45, over a period of time longer than about three months. I eventually burn out, get tired and cranky, become less effective, and get sick. Vacations are a way for me to recharge, build my energy back, explore some different things, spend extended and uninterrupted time with the most important person in my life (Amy), and just chill out. This vacation usually takes the form of a Qx Vacation that is off the grid which is now well known to everyone who works with me.

Amy and I ordinarily spend the month of July at our house in Homer, Alaska. While this isn’t “a vacation”, it’s a change of context that has become a very important part of our routine. I work while I’m there, am completely connected and available, but have a very different life tempo. And – most importantly – zero travel.

This summer we spent July in Paris. We both love Paris and went there to just “live.” We rented an apartment in the 8th, ran in the local park, shopped at the Monoprix down the block, ate lunch at all of the nearby restaurants, and had some amazing meals out. But mostly we just hung out, worked remotely, and spent time together.

I’ve had a fantasy about renting a house in the Tuscan countryside and spending a month in Tuscany for many years. We decided to do it this summer and we turned our month in Alaska into two months in Europe. However, rather than travel around and be tourists, we just lived. We had plenty of friends visit, but we spent the days exercising (I ran a lot), reading, writing, and working.

I plan to write at least one post about what I learned in my “summer in Europe” after I return to the US next week. It has been an amazing experience, especially since I was completely connected to my regular work, yet was able to observe a lot of activity from a distance and reflect on what I really thought was going on.

In the mean time, if you are a leader, entrepreneur, or anyone else, I hope you read Kanter’s post and think hard about both the value of time away and the expectation setting around it. Life is short – make sure you live it.

It’s Sunday morning. Take a deep breath. It’s summer time. Go for a walk. Or a run. Play with your family. Take a nap this afternoon. Read a book. Go to a movie. Chill.

Last week, I had two close friends tell me some version of “I’m too busy.” One insightfully said “I have no time these days. I’m doing too much.” The other simply said “sorry I didn’t call back – I have no time.”

I too am intensely busy. And anyone who knows me knows that I eventually hit a wall, have short term burnout, need to rest / recover, and then get back at it. However, as I’ve gone through this cycle throughout my life, I’m getting smarter about how to handle it. My week a quarter off the grid helps. July in Alaska helps (although this summer has a fun, European twist). Running helps. Time with Amy helps. And recognizing that as one gets busier, more crap creeps into the schedule, is important.

I’ve deliberately slowed down in June. I’ve cancelled a bunch of unnecessary things. I’m rethinking how I approach board meetings which are a massive time suck for any VC. I’ve been a lot more hesitant to say yes to a trip somewhere to do something. I’ve been aggressively using Skype and Google Video Chat for meetings. And I’m scheduling a lot less throughout the day – trying to have more adhoc time to work on whatever I feel like or whatever comes up.

Basically, I’m trying to slow down. If I do this right, I believe I’ll be able to cover even more ground. I think this applies to any entrepreneur, or anyone involved in the entrepreneurial ecosystem. “Being really busy” is seductive – it has nothing to do with getting things done, or actually accomplishing your goals. But there’s something satisfying, or at least addictive, about being so busy that you don’t have time to think or reflect on what is going on around you. This is a big mistake long term as you’ll ultimately make crummy decisions.

Slow down to speed up.

Last night I had dinner with my brother Daniel, one of the partners at Slice of Lime, a Boulder-based web design and development firm. He and I were at TechStars at the end of the day where I gave a talk on “How To Be A CEO.” Afterwards, we had a nice dinner together at The Cheesecake Factory (his choice – I don’t think I’d been there in a decade – and it was surprisingly good), a great talk, and dynamite brother hang out time.

We do this once a month and have committed to each other to try to do this every month for the rest of our lives. For the first 25 years of my life we weren’t that close. While I don’t remember being an asshole older brother, I’m periodically reminded by Daniel about things I did that, while they fall in the “typical older brother” category, also could be consider major asshole moves. We became very close when he moved to Boulder 15 years ago (less than a year after I did) and we’ve never looked back.

We’ve modeled our relationship after our father (Stan) and his brother (Charlie). I’m very close to both my dad, who is one of my best friends, but also very close to Charlie who introduced me to computers when I was 11 and has been a great mentor to me, always inviting me along to meetings with major companies like Lotus, Microsoft, IBM, and DEC when he was the CIO at Frito Lay in the 1980′s. In 2000, Charlie and I became business partners when Mobius Venture Capital invested in The Feld Group and I joined the board. Over the next four years, I worked closely with Charlie and his partners at The Feld Group as they built the company before selling it to EDS in 2004.

While I’ve always viewed my relationship with my dad and Charlie as special, part of what drives that is their incredibly close relationship. My dad is older by about the same amount that I am older than my brother and, while there is the typical older brother / younger brother entertainment, these two guys completely have each other’s back, no matter what. Whenever my dad tells me he’s heading out to Charlie’s farm to hit baseballs (Charlie has a baseball diamond on his property), I can hear the joy and excitement of the kid from the Bronx who taught me how to hit a baseball in his voice.

So Daniel and I try hard to emulate the relationship and take it to another level. While we talk plenty about business stuff, we also spend a lot of time talking about our lives, what is driving us, what stresses us out, and what we strive to do better. We talk about things that only brothers can talk about and instinctively know when the other needs help and support. Often – we just hang out.

As I sit at my desk at my office in Boulder at the end of a Friday of another intense week, I think about how lucky I am to have role models like my father and his brother, both for themselves as individuals and for their relationship. Daniel – thanks for being an awesome brother. And dad and Charlie – thanks for leading the way!

This morning, as I cranked through my 5am – 7am routine (which ends at 6am today because I have to leave the house at 630am to get to CU Boulder to give a keynote at the 2011 Boulder Economic Summit) I kept thinking to myself “deep breath.” If you do yoga you know exactly what I’m talking about – it’s part of Amy’s mantra for each of us to relax, slow down, and concentrate.

I’m in a particularly intense work phase that I expect will run through the end of June based on a few things that are going on that will happen between now and then. On top of it, I’m trying to run two marathons in May (Cincinnati, which I did already – and it sucked, and Madison, which is coming up at the end of the month.) Between all the work and travel, I’d probably already be pretty tired, but layer the running and the marathons on top of it and I’m physically exhausted.

While I contemplated punting on the second marathon, there are a few things driving me to do it, including really understanding my own recovery dynamics. I have a hypothesis about how I recover from a marathon (quickly) but I haven’t tested it. By adding a second marathon on top of everything else within 30 days, I’m suddenly learning some new stuff about rest, sleep, and weight. I’m also experiencing an interesting emotional spectrum that I haven’t experienced in a while (some good, some not good) that is clearly a function of the intersection of my physical activity and my work activity.

What popped out this morning is the need for more “deep breaths.” With my normal work / life rhythm, I get these on the weekend and then once a quarter when I go off the grid for a week. But given the daily work intensity combined with the physical fatigue, it’s become very obvious that I need something different during the week to sustain things at this level. Last night I blew off a dinner with a friend to just go home and lie on the couch with Amy all evening. That helped, although I spent almost all of it with an iPad in my lap sort of watching The Hangover, sort of catching up on email, and working on a few things that I knew I couldn’t jam into today.

Tonight, Amy and I have dinner alone. I’m going to shut off completely for a few hours and reflect on what I’m going through and learning about recovery. Fortunately I have a partner who puts up with this and lets me use myself as my own laboratory for these experiments.

Amy and I spent the last week at Canyon Ranch in Tucson, Arizona. It was awesome.

I was tired and needed a break. I also needed a focused week to finish the final draft of Book #2 (Venture Deals: Be Smarter Than Your Lawyer and VC) that I’m writing with my partner Jason Mendelson. The submission date is March 31st and I think we are going to be three days early.

While I wasn’t completely off the grid last week, I hid behind a different email address and didn’t check my email, or the web, or any of my traditional news and info services. It was fascinating to be able to quickly catch up using Gist as I could look at the last seven days of news for the people I cared about in the Dashboard view (they prioritized). There were a few interesting things but like most weeks there was a lot more noise than signal.

So I got to spend my entire week on signal, which consisted of three things:

1. Spend a lot of time with Amy.
2. Finish the final draft of the book.
3. Run and exercise (I rediscovered pilates).

I had huge success on all three fronts, I’m refreshed, and ready for Q2.
