I remember my son wanted to go to bed with his cowboy boots on, and we had this fight for like an hour. Then I realized that the only good reason I had for him not to do it is because I didn't want him to. There was really no other reason. And finally I said, "OK, fine." It was a great victory for me, because I realized it doesn't really matter.

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.

Now I feel and I say all the time that vanity is, like, long gone. I'm really free of worrying about what I look like, because it's out of my shaky hands. I don't control it. So why would I waste one second of my life worrying about it?

The more I expect, the more unhappy I am going to be. The more I accept, the more serene I am.

So what I say about Tracy is this: Tracy's big challenge is not having a Parkinson's patient for a husband. It's having me for a husband. I happen to be a Parkinson's patient.

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."
