Everyone should have a deep-seated interest or hobby to enrich his mind, add zest to living, and perhaps, depending upon what it is, result in a service to his country.
Dale CarnegieNo one likes to feel that he or she is being sold some-thing or told to do a thing. We much prefer to feel that we are buying of our own accord or acting on our own ideas. We like to be consulted about our wishes, our wants, our thoughts.
Dale CarnegieWhy prove to a man he is wrong? Is that going to make him like you? Why not let him save face? He didn't ask for your opinion. He didn't want it. Why argue with him? You can't win an argument, because if you lose, you lose it; and if you win it, you lose it. Why? You will feel fine. But what about him? You have made him feel inferior, you hurt his pride, insult his intelligence, his judgment, and his self-respect, and he'll resent your triumph. That will make him strike back, but it will never make him want to change his mind. A man convinced against his will is of the same opinion still.
Dale CarnegieIf you increase your success by even a mere 10 percent, you have become 10 percent more effective as a leader than you were before.
Dale CarnegieWhen we are not engaged in thinking about some definite problem, we usually spend about 95 percent of our time thinking about ourselves. Now, if we stop thinking about ourselves for a while and begin to think of the other person's good points, we won't have to resort to flattery so cheap and false that it can be spotted almost before it is out of the mouth.
