Never tell the truth to people who are not worthy of it. - Mark Twain

"All you need in this life is ignorance and confidence, and then success is sure."

"A successful book is not made of what is in it, but what is left out of it."

"In a good bookroom you feel in some mysterious way that you are absorbing the wisdom contained in all the books through your skin, without even opening them."

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

"What a wee little part of a person's life are his acts and his words! His real life is led in his head, and is known to none but himself."
