George Bernard Shaw was right. He summed it all up when he said: "The secret of being miserable is to have the leisure to bother about whether you are happy or not." So don't bother to think about it! Spit on your hands and get busy. Your blood will start circulating; your mind will start ticking-and pretty soon this whole positive upsurge of life in your body will drive worry from your mind. Get busy. Keep busy. It's the cheapest kind of medicine there is on this earth-and one of the best.
Dale CarnegieThe way to defeat fear: decide on a course of conduct and follow it. Keep so busy and work so hard that you forget about being afraid.
Dale CarnegieTell a child, a husband or an employee that he is stupid or dumb at a certain thing, that he has no gift for it, and that he is doing it all wrong and you have destroyed almost every incentive to try to improve. But use the opposite technique, be liberal with encouragement; make the thing seem easy to do, let the other person know that you have faith in his ability to do it, that he has an undeveloped flair for it - and he will practice until the dawn comes in at the window in order to excel.
Dale CarnegieLive an active life among people who are doing worthwhile things, keep eyes and ears and mind and heart open to absorb truth, and then tell of the things you know, as if you know them. The world will listen, for the world loves nothing so much as real life.
