Please live a healthy life - medicine is an imperfect science.

Nothing I study makes me think we will survive this century. And yet why am I so happy? Because it's not too late. Just get off your ass and work for revolution.

The role of a clown and a physician are the same - it's to elevate the possible and to relieve suffering.

I'm great at a deathbed. I've never given tranquillisers or psychiatric medicine. I've given love and fun and creativity and passion and hope, and these things ease suffering.

Unlike a lot of people, I don't feel powerless. I know I can do something. But anyone can do something, it's not about being special. It's about deciding to do it - to dive into work for peace and justice and care for everybody on the planet.

No one ever writes me and says, 'We have a happy hospital'. Nowhere is doing it in a healthy way. That's encouragement for me.

I'd say that I think the most revolutionary act that you can commit in our society today is to be happy.
