One of the most tragic things I know about human nature is that all of us tend to put off living.
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.
Dale CarnegieLooking at the other person's point of view and arousing in him an eager want for something is not to be construed as manipulating that person so that he will do something that is only for your benefit and his detriment. Each party should gain from the negotiation.
