Money doesn't mean anything to me. I've made a lot of money, but I want to enjoy life and not stress myself building my bank account. I give lots away and live simply, mostly out of a suitcase in hotels. We all know that good health is much more important.

I had the classic 40 meltdown, I did. It's embarrassing. It was pretty funny. But then I recovered. To me, it was like a second adolescence. Hormonally, my body was changing, my mind was changing, and so my relationship to myself and the world around me came to this assault of finiteness.

And it's easy to stay grounded. The ground is very close. And we walk on it every day.

What would happen if you melted? You know, you never really hear this talked about much, but spontaneous combustion? It exists!... [people] burn from within... sometimes they'll be in a wooden chair and the chair won't burn, but there'll be nothing left of the person. Except sometimes his teeth. Or the heart. No one speaks about this, but its for real.

When the people you love are gone, you're alone.

I have a producing partner named Stephen Hamel, and we've been trying to generate material.

I did do some things different [in John Wick 2], but it's different on basically the same things. Because I have the background from the first film, it was really the first time I was doing judo and jiu-jitsu.
