Idk… It’s not that hard for me in most situations. Even if I feel a moment of regret over a past situation or a bit of embarrassment, I just center myself with the honest truth of “No one cares, I bet no one even remembers that interaction. And if they do, fuck em anyway… who cares? It literally has no effect on your life…”
It’s a maturity thing. As a kid, it’s easier to get caught up in worrying about other people’s judgments. When you are older, you realize how worthless most people’s opinions truly are to your life. You can just live your life of peace and honesty, and fuck the haters.
