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 secret to a good marriage, as far as I am concerned, is a joke I make: Keep the fights clean and the sex dirty.

I think the scariest person in the world is the person with no sense of humor.

To be brutally honest, for much of that time, I was the only person in the world with Parkinson's. Of course, I mean that in the abstract. I had become acutely aware of people around me who appears to have the symptoms of Parkinson's disease, but as long as they didn't identify with me, I was in no rush to identify with them. My situation allowed, if not complete denial, at least a thick padding of insulation.

I truly believe that we have infinite levels of power that we don't even know are available to us.

Lance Armstrong showed up, and I started talking to him; I saw all these people with cancer who followed him to Paris for the Tour de France, and I saw the difference he was making in their lives. That put it together for me...having it be not so much about me, but [my being] a vehicle for it.

Don't spend a lot of time imagining the worst-case scenario. It rarely goes down as you imagine it will, and if by some fluke it does, you will have lived it twice.
