I'm completely on board with what you're saying. Liking yourself is important and sometimes very difficult. I used to obsess so much about not just being liked, but being the most liked. I hurt a lot of friends in my teenage years while trying to become the most popular person in the "group'. At some point in my 20s something clicked and I just stopped caring about how others thought of me. I felt confident in myself and I no-longer needed an audience to find me interesting or funny.

One of my favourite traits/quirks is making jokes that are guaranteed to bomb for anyone but myself or maybe someone who isn't present. I'll get confused looks and just say, "don't worry, the cosmos found that one hilarious."
