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.
