To do the impossible, you need to ignore the popular.

There is an infinite selection of things that I could test in life, so I generally will look for a critical mass of word that comes back to me. At this point I have hundreds of friends who are the best at what they do, arguably number one in the country or in the world. I will oftentimes just kind of throw a volley out to people, ask them what they're obsessing on or what they find interesting that's on the fringe. If the same answer comes back a few times, I'm like, "Okay."

I do my best writing between 10 p.m. and 5 a.m.. Almost every friend I have who is a consistently productive writer, does their best writing between 10 p.m. and 8 a.m. My quota is two crappy pages per day. I keep it really low so I'm not so intimidated that I never get started. I will do the gathering of interviews and research throughout the day. I'll get all my notes and materials together and then I'll do the synthesis between 10 p.m. to bed, which is usually 4 or 5 a.m.

If it's important to you and you want to do it 'eventually', just do it and correct course along the way.

At its core, I don't view Facebook as a social network. I think it could become the driver's license of the Internet. And beyond that, it can become the pipes and the plumbing upon what most of the Internet is built. I think it's very well positioned.

But if it's tolerable mediocrity, and you're like, 'Well, you know it could be worse. At least I'm getting paid.' Then you wind up in a job that is slowly killing your soul and you're allowing that to happen. Comfort can be a very, very dangerous thing.

It's not enough to have the right answers. You have to have the right questions.
