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 CarnegieIf you do something for someone else, never remember. If someone does something for you, never forget.
Dale CarnegieEverybody in the world is seeking happiness - and there is one sure way to find it. That is by controlling your thoughts. Happiness doesn't depend on outward conditions. It depends on inner conditions.
