What's your favorite part of a typical day?
Getting to work. I'm alert and awake, and there's a whole stretch of time ahead of me.

What skill would you most like to improve?
Evaluating people when I first meet them. I've always had a tendency to be much more optimistic about people than I should be. I'd like to be a little shrewder.

What makes for a good salesperson of your product?
Passion about what we're creating.

If you could go back and do something differently, what would it be?
I've done a lot of stupid things, but in most cases I can't complain about the outcomes. I wouldn't have sold my Google stock so early.

What part of your job would you gladly give up?
Anything having to do with paperwork, contracts, scheduling, or even maintaining my own computer.

What's your favorite blog (other than your own)?
I subscribe to about 200 blogs. I look for insights and good writing, and I look to get smarter. Marc Andreessen has kind of a sit-by-the-fire blog. He's one of the smartest people in the industry.

What business accomplishment are you proudest of?
Not letting Blogger die.

Who gives you the best advice on your business?
My therapist. The hardest business problems are always people problems, and she has better insights into people than anyone else I know.

What keeps you up at night?
Three things: One is my wife. Two is worries about Twitter. Three is new ideas.

What's your greatest strength as an entrepreneur?
Comfortableness with uncertainty--having a strong vision for an opportunity and faith that I'll get there.
