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.

Well, you know, I've had a very checkered career.

I truly think a long career is to keep the audience guessing and not being able to be boxed, and for me, I'm not hell-bent on playing the lead in things as long its an interesting character with phenomenally talented people, and it's a script that I feel is genuinely innovative, creative, and potentially interesting for an audience.

I don't always succeed in creating a delicious dinner for my family; I would, however, argue for the likely success of Taco Night. Who doesn't love a taco? Make it with veggie crumbles! Add fish! Have you tried ground buffalo? The results are always impressive.

I've done most of my career with Barca, with the exception of the period I played for Manchester United.
