Definition - Self-Esteem: confidence in one's own worth or abilities
You determine what your level of confidence in yourself should be. No one gets to decide that for you! I have a close friend who wakes up every morning and the first thing she does is look in the morning to tell herself how amazing she is! Because of my own insecurities, I used to think that was weird but woah, she was just ahead of the game. She was and still is so confident of herself that every morning that is the first thing she focuses on.
