This one...for me.

“Words do not express thoughts very well. They always become a little different immediately after they are expressed, a little distorted, a little foolish.”
― Hermann Hesse

“The only way you can write the truth is to assume that what you set down will never be read. Not by any other person, and not even by yourself at some later date. Otherwise you begin excusing yourself.
― Margaret Atwood, The Blind Assassin

“The pages are still blank, but there is a miraculous feeling of the words being there, written in invisible ink and clamoring to become visible”
― Vladimir Nabokov

“We write to taste life twice, in the moment and in retrospect.”
― Anaïs Nin

“Perhaps I write for no one. Perhaps for the same person children are writing for when they scrawl their names in the snow.”
― Margaret Atwood

“The most important things are the hardest to say. They are the things you get ashamed of, because words diminish them -- words shrink things that seemed limitless when they were in your head to no more than living size when they're brought out. But it's more than that, isn't it? The most important things lie too close to wherever your secret heart is buried, like landmarks to a treasure your enemies would love to steal away. And you may make revelations that cost you dearly only to have people look at you in a funny way, not understanding what you've said at all, or why you thought it was so important that you almost cried while you were saying it. That's the worst, I think. When the secret stays locked within not for want of a tellar but for want of an understanding ear.”
― Stephen King, Different Seasons

“One always has a better book in one's mind than one can manage to get onto paper.”
― Michael Cunningham
