Develop self-awareness by observing your thoughts. The first step to being less judgmental is learning to catch yourself in the act, which requires some practice with both mindfulness and self-awareness. For a few days, observe your thoughts and try to catch yourself making negative judgments about others. Look our for phrases or thoughts like: Person A shouldn’t do [action]. If I were Person A, I wouldn’t do [action]; I would do [alternative action] instead. Person A is so [negative adjective]. Once you learn to recognize these thoughts, ask yourself why you feel the need to judge the people in question.
