When we hate our enemies, we are giving them power over us: power over our sleep, our appetites, our blood pressure, our health, and our happiness.
Dale CarnegieLet's never try to get even with our enemies, because if we do we will hurt ourselves far more than we hurt them. Let's do as General Eisenhower does: let's never waste a minute thinking about people we don't like.
Dale CarnegieMillions of people have wrecked their lives in angry turmoil, because they refused to accept the worst; refused to try to improve upon it; refused to salvage what they could from the wreck. Instead of trying to reconstruct their fortunes, they engaged in a bitter and "violent contest with experience"- and ended up victims of that brooding fixation known as melancholia.
