Drawing makes you see things clearer, and clearer and clearer still, until your eyes ache.

About shadows: do we see shadows? Loads of people don't. A camera will notice a shadow, but how many people have got a shadow in front of them when they take a picture and don't notice it, and then they see it in the photograph because the photograph will catch the shadow.

I've always been a looker. Loads of people say, "I never saw that" - but that's what artists do.

I think I’m greedy, but I’m not greedy for money – I think that can be a burden – I’m greedy for an exciting life. I want it to be exciting all the time, and I get it, actually. On the other hand, I can find excitement, I admit, in raindrops falling on a puddle and a lot of people wouldn’t. I intend to have it exciting until the day I fall over.

On the 31st of October 2011 year, I had a mini-stroke. I couldn't finish my sentences. So I went to the doctor. It was a tiny one. The speech came back in a month or so.
