they also strengthen the ego in another way by giving it a feeling of superiority on which it thrives. It may not be immediately apparent how complaining, say, about a traffic jam, about politicians, about the "greedy wealthy" or the "lazy unemployed," or your colleagues or ex-spouse, men or women, can give you a sense of superiority. Here is why. When you complain, by implication you are right and the person or situation you complain about or react against is wrong.
— Eckhart Tolle
