A painting is a collection of a series of corrections.
The first thing you see is the last thing you do.
It's not what you paint. It's how you paint it. You don't have to paint elaborate things. Paint simple things as beautifully as you can.
I switched to painting with my left hand to be in better company.
It is in the contrast of light and dark that design happens.
If it's all wrong, it's all right.
