Sometimes competition can be good and drive someone to try harder or achieve something good that you might have not achieved otherwise.
I think that “trying to impress others will not make you happy” might be a more accurate advice. I’ve seen people actually build an extra floor at their house, which they do not need, “just because the neighbour did the same” … now, years later, they’d wish they could have all that wasted effort and money back, but it ain’t coming back and the neighbour is not really impressed either.
Big showy cars, useless/flashy brand products, the newest phones and gizmos, bi-annual furniture changes all to impress people that actually despise you. I am not sure what to do with these people. Some of them are loaded with cash, so “you do you” I guess, but others go heavily in debt to achieve a fake social status and it is not rare for all that junk to end up being repossesed by the bank. Those end up in a really bad state, considering how much they had made “external validation” their most important characteristic and metric of success.
I agree, although in my case that was not the only problem. I used to derive self value from doing well in competitions with others, like math olympiad, go tournaments etc.
Nowadays I still enjoy doing math and playing go, but no tragedy when I make mistakes.
It’s funny that we’re calling free will into question, but not traveling back in time…
But even in the world where time travel exists and free will does not, you can still tell your younger self things. Probably exactly what you heard from your older self earlier
