I thought I was a pretty good writer, but I didn't have anything to write about. I wanted to go out in the world, have some adventures and then write about them.

I woke up. I was like, "Look, you can do anything you want - and you want a lot of things, so you should get to work."

All I know is that when I go somewhere, I'm not an autobot. I am a human being. I am not an actor.

You have to make those mistakes. You have to do the work. You have to fail. I also realized that I should practice what I preach, which is that if you only do get one kick at the can . . . When you go to places like Africa or Asia or the Indian sub-continent, you realize that a lot of the people there don't ever get a kick at the can. There are no "kicks" at the can - you just don't have that shot.

My life, like most people's, has been negatively affected by cancer, and the thought of my young children living in an age where this is no longer humanity's No. 1 health fear was simply overpowering.
