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 CarnegieIt isnโt what you have or who you are or where you are or what youโre doing that makes you happy or unhappy. Itโs what you think of it. Two people may in the same place doing the same thing, and yet one may be miserable and the other happy. Why? Because of a different mental attitude.
