Let's cease thinking of our accomplishments, our wants. Let's try to figure out the other man's good points. Then forget flattery. Give honest, sincere appreciation. Be hearty in your approbation and lavish in your praise, and people will cherish your words and treasure them and repeat them over a lifetime - repeat them years after you have forgotten them.
