Whether you think you can or think you can't, you're right.
Johann Wolfgang Von Goethe
Who is sure of their own motives can in confidence advance or retreat.
Whoever does not regard what he has as most amply wealth, is unhappy, though he be master of the world.
You are educated when you have the ability to listen to almost anything without losing your temper or self-confidence.
Brian G. Jett
You can determine how confident people are by listening to what they don't say about themselves.
You cannot consistently perform in a manner which is inconsistent with the way you see yourself.
You have to expect things of yourself before you can do them.
You have to have confidence in your ability, and then be tough enough to follow through.
You need to play with supreme confidence, or else you'll lose again, and then losing becomes a habit.
William Dean Howells
You'll find as you grow older that you weren't born such a great while ago after all. The time shortens up.
Frank Lloyd Wright
Youth is a circumstance you can't do anything about. The trick is to grow up without getting old.
You've got to take the initiative and play your game. In a decisive set, confidence is the difference.
