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.

The role of the board is advice and consent. If the CEO does not lay out a clear strategy and tries to get the board to set one, it will usually end in disaster.

The best source by far for hiring is people that you already know and people that other employees in the company already know.

In general, it's best if you're building something that you yourself need.

I believe in fighting with investors to reduce the amount of equity they get and then being as generous as you possibly can with employees.

... how much time you should be spending on hiring? The answer is 0 or 25 percent.

You think you have this great idea that everyone's going to come join, but that's not how it works.
