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.

Everything does come from nature. That's where you get new ideas. Just draw the landscape. I felt doing it with a bit of burnt wood was also good because I was drawing burnt wood with a piece of wood. I wanted to do black and white. After using color, I thought black and white would be good. You can have color in black and white. There is color in them, actually.

I believe that the very process of looking can make a thing beautiful.

Style is something you can use, and you can be like a magpie, just taking what you want. The idea of the rigid style seemed to me then something you needn't concern yourself with, it would trap you.

Drawing takes time. A line has time in it

I was aware that the teaching of drawing was being stopped almost 30 years ago. And I always said, 'The teaching of drawing is the teaching of looking.' A lot of people don't look very hard.

I was always struck by how Picasso had no interest in music.
