It's better to be at the bottom of the ladder you want to climb than at the top of the one you don't.

Stephen Kellogg

If a person says I have worked hard but have not found [success], don't believe him. [If a person says] I have not exerted myself, and I have found [success], don't believe him. [If he says] I gave it my all and I have found [success], believe him!

Megillah 6b

If you think you can do it, you can.

John Burroughs

A sign of wisdom and maturity is when you come to terms with the realization that your decisions cause your rewards and consequences. You are responsible for your life, and your ultimate success depends on the choices you make.

Denis Waitley

If you believe it will work out, you'll see opportunities. If you believe it won't, you will see obstacles.

Wayne Dyer
