"No one but myself knows the anxiety I go through and the trouble I give myself to finish paintings which do not satisfy me and seem to please so very few others."

"I'm so fed up with painting. I wish I had never started."

"I am working very hard, struggling with a series of different effects, but at this time of year the sun sets so fast that I cannot keep up with it."

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

"I'm absolutely furious. Everything is going wrong."
