The mindset that "I don't need you"

If you genuinely live a life where you got exciting/self fulfilling stuff going on, you can walk away from anyone and youll be fine if not better off.

I used to sweat shit all the time, super nervous about getting a positive outcome, and just acting kind of needy.

However, the other day I was hanging out with some friends I'm usually kind of nervous around and I realized, "I really don't give a shit if these people kick me out of their group or think I'm weird, I got a copy of The Witcher 3 waiting for me at home and a sky diving trip coming up, I don't need them for anything."

Instantly I became more funny and less caring about little fuck ups and miserable over little bull shit awkwardness.

Give it a shot.

And if it doesn't work, make sure you actually build a life that can lead you to look at anyone and say "I don't need you."
