I vibe with a lot of what you said and am also working on similar things.
I think if I had any disagreement it would mostly be about the label of "selfishness" which often has a negative sort of definition. Maybe you could call it Mindful Self Love instead?

I've definitely been working on self love a lot recently and have been more and more appreciating my own company and focusing on myself and my needs.

So I definitely think there's some great wisdom in that approach as I have been eperiencing it first hand, though I still think empathy is super important as well so like many things in life it seems to be a balance! If you're too far in either direction is could be a problem.

Great post, I think this is a very helpful subject for many people and I like reading more about it.

By the way. I left a message for you on Discord. I shoulda asked you sooner as it is somewhat time sensitive, but anyways... I'm hoping you can respond within a couple of days?
