When you’re in school, every little mistake is a permanent crack in your windshield. But in the real world, if you’re not swerving around and hitting the guard rails every now and then, you’re not going fast enough. Your biggest risk isn’t failing; it’s getting too comfortable.

If you have a dream, you can spend a lifetime studying, planning, and getting ready for it. What you should be doing is getting started.

Where you live matters: there’s only one MIT. And there's only one Hollywood and only one Silicon Valley. This isn't a coincidence: for whatever you're doing, there's usually only one place where the top people go. You should go there. Don’t settle for anywhere else.

You have to adopt a mindset that says, 'Okay, in three months, I'll need to know all this stuff, and then in six months there's going to be a whole other set of things to know - again in a year, in five years.' The tools will change, the knowledge will change, the worries will change.

You become the average of the five people you hang out with.

If you start your own thing, you can learn a lot really fast from doing things wrong.
