I didn't just want to be a poster boy and sign on to publicize somebody else's method of operations. If I was going to put myself out there, I wanted to make sure that it was to an end. So I got involved with this congressional hearing about Parkinson's being underfunded.

My happiness grows in direct proportion to my acceptance, and in inverse proportion to my expectations.

If I were overweight because I ate too much, I would have far more of a complex. I would know if I just stopped eating and showed a little discipline I would be thin. But there's not a hell of a lot I can do about being short. You just gotta run with it.

I'm a dad, I'm a husband, I'm an activist, I'm a writer and I'm just a student of the world.

In fact, Parkinson's has made me a better person. A better husband, father and overall human being.

To be associated with a film that just flat-out makes people happy is such a blessing and a tremendous privilege, and I'll always be grateful for it. People's eyes light up when they talk about it. I've been in Asia, Africa, Europe and even Bhutan; people know the movie there. It's just an amazing thing.

I can't be smug, because I know that you can lose anything at any point. And I can't be angry, because I haven't lost it.
