Some people can't learn to play the guitar by reading a book. You have to actually try to manage a bit and you won't do well at first.

I think you must have your own office. I don't believe ever in shared office spaces.

The real thing you do is you ask a lot of questions.

You generally know when someone asks you to do something- am I more writing, or am I more editing? The editor is the best metaphor for your job.

Ultimately, I don't believe that you can build a company without a lot of effort, and that you need to lead by example.

Your goal over time is to use less red ink every day.

There are three things you need to do as a CEO-founder. Think strategically, drive design, and drive technology. Some people who are really good at one can build a pretty foundational company. Most people who are very successful are good at two. But Jack is the only person in the Valley I've met who's all three. He's a first-rate strategist, a first-rate designer, and a first-rate technologist.
