The way life runs through everything, even the tiniest elements of nature - that makes me humble. It's the same humility that causes people at a certain time every day to get on their knees and put their foreheads on the ground in honor of something or someone.

I always feel very connected to Canada. My reference for everything is my Canadian background, my life in Canada. Particularly on this issue of refugee immigration: I couldn't be prouder of Canada.

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.

I can't always control my body the way I want to, and I can't control when I feel good or when I don't. I can control how clear my mind is. And I can control how willing I am to step up if somebody needs me.

I don't think [Parkinson's] is Gothic nastiness. There's nothing on the surface that's horrible about someone with a shaky hand. There's nothing horrible about someone in their life saying, "God, I'm really tired of this shaky hand thing" and me saying, "Me, too." That's our reality. We have no control over it.

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