[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!

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.

I like to encourage people to realize that any action is a good action if it's proactive and there is positive intent behind it.

There are no moments you have frozen in amber. It's moving, it's changing, so appreciate what's good about right now and be ready for what's next.

My whole life, meeting people is like a blind date, because I feel like they've already seen the video on me.

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've never gotten up to see something one of my kids wanted to show me and not been rewarded.
