How to improve my self esteem?

I have done a lot of work on myself. I always try to think positively, I assert myself as best as I can. I try my best not to allow people to disrespect me. In addition to that, most of my reasons for poor self esteem are irrational. I have achieved the things I used to be insecure about but I keep subconsciously moving the goalposts. I just started keeping a gratitude journal as well.

I just want good self esteem
