In all the difficult decisions that I made through the course of running Loudcloud and Opsware, I never once felt brave. In fact, I often felt scared to death. I never lost those feelings, but after much practice, I learned to ignore them. That learning process might also be called the courage development process.

In my experience as CEO, I found that the most important decisions tested my courage far more than my intelligence.

Leadership is hard to train on.

I do think a lot of people are trying to do important things still, and I think it is really a great thing that entrepreneurship is getting easier. When I started, it was just much harder to begin a company.
