You've probably read in People that I'm a nice guy - but when the doctor first told me I had Parkinson's, I wanted to kill him.

I think there's a God and I know it's not me.

Ironic that in order to do my life's work, I had to quit my day job.

There's an idea I came across a few years ago that I love: My happiness grows in direct proportion to my acceptance and in inverse proportion to my expectations. That's the key for me. If I can accept the truth of 'This is what I'm facing - not what can I expect but what I am experiencing now' - then I have all this freedom to do other things.

When something enters your life that is so big and so non-negotiable as catastrophic illness, you either go in denial for a while or ultimately you accept it and you make space for it. And in making space for it, you illuminate a lot of things that you normally don't have room for you simply just look at the world differently.

The purpose that you wish to find in life, like a cure you seek, is not going to fall from the sky. ...I believe purpose is something for which one is responsible; it's not just divinely assigned.

The way I look at life, and the way I look at the reality of Parkinson's, is that sometimes it's frustrating and sometimes it's funny. I need to look at it that way, and I think other people will look at it that way.
