I don't burden myself too much with others' expectations - or even my own expectations. I think your happiness grows in direct proportion to your acceptance, and in inverse proportion to your expectations. It's just a matter of putting one foot in front of the other - or doing the next right thing, so to speak.

You know what's cool? My kids think I'm ordinary.

With Parkinson's, it's like you're in the middle of the street and you're stuck there in cement shoes and you know a bus is coming at you, but you don't know when. You think you can hear it rumbling, but you have a lot of time to think. And so you just don't live that moment of the bus hitting you until it happens. There's all kinds of room in that space.

Life is good, and there's no reason to think it won't be--right up until the moment when everything explodes into a fireball of tiny, unrecognizable fragments, or it all goes skidding sideways, through the guardrail, over the embankment, and down the mountain. This will happen (and probably more than once).

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.

[Constant curiousity leads to happiness:] I wake up curious every day and every day I'm surprised by something. And if I can just recognize that surprise every day and say, 'Oh, that's a new thing, that's a new gift that I got today that I didn't even know about yesterday,' it keeps me going. It keeps me more than going. It keeps me enthusiastic and grateful!

It is ironic that in the same year we celebrate the 50th anniversary of the discovery of DNA, some would have us ban certain forms of DNA medical research. Restricting medical research has very real human consequences, measured in loss of life and tremendous suffering for patients and their families.
