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

... fire fast when it's not working. It's better for the company, it's also better for the employee.

It's difficult to get large groups of people, to the extreme levels of focus and productivity that you need, for a startup to be successful.

If you don't love and believe in what you're building, you're likely to give up at some point along the way.

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.

... you can think about that for everyone you hire: will I bet the future of this company on this single hire? And that's a tough bar.

A board member of mine used to say sales fix everything in a startup, and that is really true.
