As long as you are not yourself, you can not have self-esteem
This means that if you currently do not have self-esteem, you probably aren’t yourself right now.
Instead, you are the story you’re telling yourself.
In order to regain your self-esteem, you have to be yourself again, however you are.
Find out who you really are and then be it, whatever expectations from others or yourself there might be.
Inspired by Ajahn Brahm’s talk No-Self Esteem.
