An entrepreneur must deal with more uncertainty than a professional with a well-defined role.

When I was starting out, I followed along the path that seemed to be marked out for me - from high school to college to law school to professional life.

People don't want to believe that technology is broken. Pharmaceuticals, robotics, artificial intelligence, nanotechnology - all these areas where the progress has been a lot more limited than people think. And the question is why.

Credentials are critical if you want to do something professional. If you want to become a doctor or lawyer or teacher or professor, there is a credentialing process. But there are a lot of other things where it's not clear they're that important.

We have been learning since we were children how to make money, buy things, build things. The whole education system is set up to teach us how to think, not to feel.

Teaching is the royal road to learning.

I had a really fantastic time shooting 'Bad Teacher.' I loved every second of it.

I like to tell kids that I started thinking about stories when I first started reading stuff like Dr. Seuss and 'Go, Dog. Go!,' thinking, 'Oh yeah, that's funny. I'd like to do that.' And then writing throughout school, but at the same time I was studying pre-med stuff, because my mom told me I should be a doctor.
