I owned a Ferrari, a Range Rover, a Mercedes 560SL convertible, a Jeep Cherokee and a Nissan 300ZX. I can't remember the intricate decision tree I had to climb in order to determine which one to drive to work on any given day - it probably had something to do with the weather, or which car had more gas in the tank, or upholstery that best matched whatever shirt I happened to throw on that morning.

One of the great things about Parkinson's, in a superficial way, is it relieved me of vanity. I don't worry about what I look like, because it's literally out of my hands. But on a deeper level, it gives you a real humility, because you have to deal every day with the fact that you compromise.

The moment I understood this - that my Parkinson's was the one thing I wasn't going to change - I started looking at the things I could change, like the way research is funded.

A creative mess is better than idle tidiness.

I think there's a God and I know it's not me. I don't have a set of tenets, but I live an ethical life.

A lot of times, when you have a disability, one of the things you deal with is other people's projections of what your experience is and their fear about it, and not seeing the experience you're having. There's nothing horrifying about it to me. It is what I deal with. It is my reality and my life, but it's not horrible.

I might have skipped class, but I didn't miss any lessons.
