I appreciate this post, though what I'd like to say is that low-self esteem is a multi-faceted problem that starts with our core beliefs about ourselves and includes both conscious and unconscious biases.

But I will just mention here how I overcame my own self-esteem issues - I addressed two problems within my core beliefs about self-worth. The first belief I addressed was how self-worth related to my failures - to solve this I tied my failures to self-growth and the idea of being a better person, in other words, recognizing my failures would inevitably help me grow as a person since I could resolve those failures and learn from them.

The second thing I did was develop my concept of self-compassion. Many people have negative self-talk which tends to cause a low-self esteem, so I changed my self-talk to be more encouraging and I also recognized that there's an emotional investment tied to self-talk, and that emotional investment can be helpful or harmful depending on the words I use, so I use encouraging words instead of detrimental ones.

Finally, I realized the inherent humanness of having flaws, the unique perspectives they bring, and the fact that perfection is impossible, these thoughts allowed me to see everyone as equal and unique. Everyone is growing at their own unique pace and everyone only needs encouragement to be better or do better, since seeking approval is fairly normal for people to do.

Though that is what helped me, I could elaborate more if need be, but there is no end to how we can improve our beliefs. I've written quite a lot about it on my profile if you're interested in learning more.
