self-esteem is the confidence in one's own worth or abilities; self-respect.
self-esteem is made up of the thoughts, feelings, and opinions we have about ourselves. That means self-esteem isn't fixed. It can change, depending on the way we think. Over time, habits of negative thinking about ourselves can lower self-esteem.
