...Be grateful for what you have to be thankful for instead of complaining about the little things that annoy you.
Dale CarnegieYou and I are standing this very second at the meeting place of two eternities: the vast past that has endured forever, and the future that is plunging on to the last syllable of recorded time. We can't possible live in either of those eternities - no, not even for a split second. But, by trying to do so, we can wreck both our bodies and our minds. So let's be content to live the only time we can possible live: from now until bedtime.
Dale CarnegieWe nourish the bodies of our children and friends and employees, but how seldom do we nourish their selfesteem? We provide them with roast beef and potatoes to build energy, but we neglect to give them kind words of appreciation that would sing in their memories for years like the music of the morning stars.
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.
