How to Stop Caring About Others' Opinions?

Realize that everybody has a skeleton in their closet & that people in glass houses shouldn't throw stones

One thing that helped me (born female) was I was taught to look pretty and be up to standard for men. And I thought to myself that's stupid. And rly I just got the whole mindset of screw the patriarchy the only reason certain looks or actions are weird is because it doesn't fit a social standard thats based off how men think we need to behave, and I find that ridiculous. So I started doing things that I wanted but others might find weird simply out of spite. I told myself I was making a statement and sticking it to judgmental assholes. That didnt make me immediately stop caring but I realized the reason I cared was ultimately stupid and that helped me take baby steps toward caring less. I hope this helps💕
