First ask yourself: What is the worst that can happen? Then prepare to accept it. Then proceed to improve on the worst.
Dale CarnegieOnce you have made a careful decision based on facts, go into action. Don't stop to reconsider. Don't begin to hesitate, worry, and retrace your steps. Don't lose yourself in self-doubting which begets other doubts. Don't keep looking back over your shoulder.
