Every time I act on a fear, I feel disappointed in myself. I have a lot of fear. If I can quit all fear in my life and all guilt, then I tend to be much, much more living up to my standards. I've never seen a person fail if they didn't fear failure.

In 50 years, there will be only 10 institutions in the world delivering higher education and Udacity has a shot at being one of them.

I've developed my passion for cars that drive themselves from being stuck in traffic for many, many, many hours of my life. I don't know what it adds up to, but I feel like I've lost a year or two just in traffic. That's big to me. That's a lot of time, a lot of money that I just lose on the road.
