I think we all get our own bag of hammers. We all get our own Parkinson's. We all have our own thing. I think that we'll look at it through the filter of that experience, and we'll say, "Yeah, I need to laugh at my stuff, too."

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.

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.

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.

That's the way I look at things - if you focus on the worst case scenario and it happens, you've lived it twice. It sounds like Pollyanna-ish tripe but I'm telling you - it works for me.

Medical science has proven time and again that when the resources are provided, great progress in the treatment, cure, and prevention of disease can occur.

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.
