Agatha Christie, An Autobiography

"I suppose it is because nearly all children go to school nowadays and have things arranged for them that they seem so forlornly unable to produce their own ideas."

"There was a moment when I changed from an amateur to a professional. I assumed the burden of a profession, which is to write even when you don't want to, don't much like what you're writing, and aren't writing particularly well."

"It is a curious thought, but it is only when you see people looking ridiculous that you realize just how much you love them."
