Life is supposed to be filled with unhappiness and uncertainty. The small guy never wins. This is the way things are supposed to be. There are winners and losers in all transactions between people. My role in life is to be a loser.
Most people are basically selfish, mean, self-centered and disrespectful.
You should never complain. Be silent with your feelings. Know they are being abused but are so used to it they can't visualize life any differently. Lack belief in themselves or in others. Lack knowledge of assertiveness and may be either extremely passive or overly aggressive with their antagonists.
