Adolf Hitler Don't mind criticism. Seven days without laughter makes one weak. Every now and again take a good look at something not made with hands a mountain, a star, the turn of a stream. There will come to you wisdom and patience and solace and, above all, the assurance that you are not alone in the world. Our attitudes control our lives.
Attitudes are a secret power working twenty-four hours a day, for good or bad.
It is of paramount importance that we know how to harness and control this great force. It is more important than appearance, giftedness, or skill.
