The best people know that they should join a rocketship.

One of the keys to focus, and why I said cofounders that aren't friends really struggle, is that you can't be focused without good communication.

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

At the beginning, you should only hire when you have a desperate need to.

As you grow, the productivity I think, goes down with the square of the number of employees if you don't make an effort.

The second part of how to hire: try not to.

Two other things that we hear again and again from our founders, they wish they had done earlier, and that is... simply writing down how you do things and why you do things.
