"I'm struggling, I'm fighting, I'm working like a madman, but I'm not getting anywhere."

"Ah, gentlemen, I do not receive guests when I'm working, indeed. When I work, if I am interrupted, I lose all inspiration; I am lost. You understand, I'm chasing a band of colour."

"I'm completely worn out. I can't go on like this."

"When you go out to paint, try to forget what objects you have before you, a tree, a house, a field or whatever."

"I can only draw what I see."
