“The two hardest things about writing are starting and not stopping.”
“Writing isn’t fun. It’s the hardest work in the world. The very, very hardest. I mean creative writing. If it’s reportorial, it’s a different thing. When you have to create a whole milieu, with characters and background, that’s a different thing entirely. … Oh, you start out all enthusiastic. But after two or three chapters it becomes plain drudgery. I worked about ten hours the other night just on correcting and rewriting, because what you write originally is just a shadow of what you had in mind.”
1970s-, The Captains, the Kings, and Taylor Caldwell (1978)

Context: The hardest thing to do is to write straight honest prose on human beings. First you have to know the subject; then you have to know how to write. Both take a lifetime to learn, and anybody is cheating who takes politics as a way out. All the outs are too easy, and the thing itself is too hard to do.
