Easier said then done, granted.
I spent all my teenage years caring what people think, but now. I couldn’t give a f*ck. And here’s how to do it.
For a start, stop asking. The second you ask someone whether this suits you, whether you came off too strong or even just listen to the gossip circulating about you, remember that you are inviting that person to impose their opinion upon yours. Don’t ask and you’ll never know. Ignorance is bliss, right?
Remember that no-one actually cares
Unfortunately, no-one cares about anyone as much as they care about themselves. We live surrounded by the most narcissistic people this planet has ever seen and they do not care what you’re wearing, they care about what they are wearing. Anyway even if they did care to spend a few minutes thinking about you, psychology says we have (on average) 50,000 thoughts per day. Meaning if someone thought of you ten times, that's only 0.02% of their overall thoughts that day, and that’s not something to flap about is it?
Everyone is different
What impresses me, probably doesn’t impress you. What I think rude, you may think courteous. What I find trendy, you might find tacky. Point is, you will never ever please everyone. So don’t waste your time trying.
