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.

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.

The least amount of judging we can do, the better off we are.

I mean, I enjoy my work as an actor. But to make a difference in people's lives through advocacy and through supporting research - that's the kind of privilege that few people will get, and it's certainly bigger than being on TV every Thursday for half an hour.

In my 50s I'll be dancing at my children's weddings.

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.

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.
