William James

"Most people never run far enough on their first wind to find out they've got a second."

"To change one's life, start immediately, do it flamboyantly, no exceptions."

"Act as if what you do makes a difference. It does."

"The greatest discovery of our generation is that human beings can alter their lives by altering their attitudes of mind. As you think, so shall you be."

"The deepest craving of human nature is the need to be appreciated."
