Developmental psychology 101: how you feel about yourself is a learned trait influenced by the treatment or mistreatment, words and actions of outside influences.

That advice is correct. You, as an individual, are responsible for your feelings and any resulting behavior. Taking advice from others is important but must be properly evaluated. The problem lies in the lack of ability to reason with logic. In general wahmyn are influenced more by their feelings. The feminization of society has resulted in many men being plagued with the same lack of logical reasoning, thus being a slave to emotion.
