Optimism is a cure for many things.

The thing that brings people to wail at a wall, or face Mecca, or to go to church, is a search for that feeling of purity.

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.

If you have doubts about someone, lay on a couple of jokes. If he doesn't find anything funny, your radar should be screaming. Then I would say be patient with people who are negative, because they're really having a hard time.

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.

It’s all about control. Control is illusory. No matter what university you go to, no matter what degree you hold, if your goal is to become master of your own destiny, you have more to learn. Parkinson’s is a perfect metaphor for lack of control. Every unwanted movement in my hand or arm, every twitch that I cannot anticipate or arrest, is a reminder that even in the domain of my own being, I am not calling the shots. I tried to exert control by drinking myself to a place of indifference, which just exacerbated the sense of miserable hopelessness.
