Two things.
1) Don’t sweat the small stuff.
2) It’s all small stuff.
Learning not to give a shite what others – especially strangers – think was an epiphany for me. This is key:
Turns out I was wrong, someone did find them funny – he did! He’d laugh his arse off, not giving a single shit whether we found it funny or not.
As a kid you wonder why your dad goes out “dressed like that” – thing his, he’s worked out that the answer to “people will look at you” is “so what?” No-one died, no-one got hurt. Who really gives a crap whether someone you’ll never see again thinks “wow, that’s a daft hat?”
The other thing I realised was that a constant source of incandescent rage was a couple of toxic people in my life. “Friends” that were really born of circumstance, you went to school with them or some such. Life’s too short to put up with that crap, get shut of them and your life will be immeasurably better.
