“Write what you know will always be excellent advice for those who ought not to write at all. Write what you think, what you imagine, what you suspect!”

“To write a good love letter, you ought to begin without knowing what you mean to say, and to finish without knowing what you have written.”

“Write what you know.”

“Write about what you don't know about what you know.”

“Write it, damn you, write it! What else are you good for?”

“Write what you know, and what do you know better than your own secrets?”

“All you can write is what you see.”

“Write only if you cannot live without writing. Write only what you alone can write.”

“There's a difference between writing for a living and writing for
life. If you write for a living, you make enormous compromises….
If you write for life, you'll work hard; you'll do what's honest,
not what pays”

“When it comes to people -- don't write about who you know; but what you know of human nature.”
