Great execution is at least 10 times more important and a 100 times harder than a good idea.

Firing people is one of the worst parts of running a company. Actually in my own experience, I think it is the worst.

The track record for founders that don't already know each other is really bad.

You also want people who are maniacally determined and that is slightly different than having a risk tolerant attitude.

You should think about for the next 10 years, you're going to be giving out 3-5% of the company every year.

If you have several ideas that all seem pretty good, work on the one that you think about, when you're not trying to think about work.

People that are really smart and that can learn new things can almost always find a role in the company as time goes on.
