Leadership is hard to train on.

As a startup CEO, I slept like a baby. I woke up every 2 hours and cried.

You can take somebody's job, you have to take their job, but you don't have to take their dignity.

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

The important thing about mobile is, everybody has a computer in their pocket. The implications of so many people connected to the Internet all the time from the standpoint of education is incredible.

The most important thing you can learn as CEO- one of the hardest things to do is, you have to discipline yourself to see your company... through the eyes of the people that you're working through. Through the eyes of the employees, through the eyes of your partners... through the eyes of the people who you're not talking to and who are not in the room.

The only thing that prepares you to run a company is running a company.
