Never allow someone to be your priority while allowing yours... - Mark Twain

"Don't go around saying the world owes you a living. The world owes you nothing. It was here first."

"Wrinkles should merely indicate where the smiles have been."

"A big leather-bound volume makes an ideal razorstrap. A thing book is useful to stick under a table with a broken caster to steady it. A large, flat atlas can be used to cover a window with a broken pane. And a thick, old-fashioned heavy book with a clasp is the finest thing in the world to throw at a noisy cat."

"Education: that which reveals to the wise, and conceals from the stupid, the vast limits of their knowledge."

"I was gratified to be able to answer promptly, and I did. I said I didn’t know."
