A jade stone is useless before it is processed; a man is good-for-nothing until he is educated.

Your most unhappy customers are your greatest source of learning.

I’m not afraid of dying, I’m afraid of not trying.

One day your life will flash before your eyes. Make sure it is worth watching

Go confidently in the direction of your dreams. Live the life you have imagined.

I cannot give you the formula for success, but I can give you the formula for failure
