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.

Happiness is a decision.

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.

As much as Parkinson's is about movement, the end stage is being frozen. So the more I let that happen, the more I'm gonna be stuck within that and unable to reverse it.

I've learned some exciting things - mostly, that people really want to help each other; and that, if you can lay out a vision for them - and that vision is sincere and genuine - they'll get interested.

My natural state is one that's affected by the shortage of dopamine production in my brain. So my natural state is to be halting and at times tremulous and kind of just physically disturbed. I mean, that's my natural state, given the situation in my brain. But I'm always as happy either way. And so when it comes to me, body language lies.

In fact, Parkinson's has made me a better person. A better husband, father and overall human being.
