"I'm having a very bad time just now; everything is going wrong, and I'm very much afraid I shall have to give it all up."

"I want to paint the light, and I want to paint the air."

"I'm absolutely exhausted. I haven't slept in days."

"I must have flowers, always, and always."

"It's on the strength of observation and reflection that one finds a way. So we must dig and delve unceasingly."
