The great use of life is to spend it for something that will outlast it.

Never suffer an exception to occur till the new habit is securely rooted in your life. Each lapse is like the letting fall of a ball of string which one is carefully winding up; a single slip undoes more than a great many turns will wind again.

To change one's life: 1. Start immediately, 2. Do it flamboyantly, 3. No exceptions.

Psychology is the Science of Mental Life, both of its phenomena and their conditions.

The greatest revolution of my life is the discovery that individuals can change the outer aspects of their lives by changing the inner attitudes of their minds.

Man can alter his life by altering his thinking.
