Self-love means accepting yourself as a worthy person. You may be thinking that all of this talk about self-love involves a form of obnoxious behavior akin to ego-mania. Nothing can be further from the truth. Self-love has nothing to do with the sort of behavior characterized by telling everyone how wonderful you are. This is not self-love, but rather an attempt to win the attention and approval of others. It is just as neurotic as the behavior of the individual who is overloaded with self contempt.
Boastful behavior is motivated by others, by an attempt to gain their favor. It means the individual is evaluating himself/herself on how others see them. If they were not, they would not feel the need to convince them. Self-love means you love yourself. It doesn't demand the love of others. An internal acceptance is sufficient.
