People always choose what seems to be the best choice to them, although their choices may be based on faulty data.

This is a variation on the previous theme. Instead of thinking people are unintelligent or selfish, assume that they did the best they could in the situation, with the tools they had. However, remember the saying, “If you do what you’ve always done, you’ll get what you always got.” Try to learn from each situation and grow with each experience.
