Life, to me personally, I believe it is a finite thing, my consciousness, and I want to use it as much as possible.

We very quickly forget about the wonderful things we've got. People lose their excitement because there's too much. Basically we're experiencing nothing, because everything is available to us.

Not since Jimmy Carr have I seen a cold computer programme on stage generate so much laughter.

My life is constant revision but it's not revision, a lot of it is for the first time.
