The only path by which another person can upset you is through your own thought.

Life is like riding a bicycle. To keep your balance, you must keep moving.

Think good, and good follows. Think evil, and evil follows. You are what you think all day long.

Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

Change your thoughts, and you change your destiny.
