One of the most popular copes is finding a semo-obscure hobby and then getting "good" at. I see a lot of people, myself included, who have taken this as a sign that maybe it isn't completely over. That couldn't be further from the truth however. If you were truly GOOD at something it would be notable, however many people are actually much better at that obscure task you're doing. You've tricked yourself by using the smallest sample possible, yourself, into believing that you're good at something. Maybe there's a handful of incels who are truly skilled but most of us are just trash.
I mean, it depends what you mean by obscure and notable.
If you are talking about skills or hobbies which require no skill or discipline, you are right.
If you are talking about things like collecting Baseball cards, playing video games, collecting stamps, learning about trains, yeah, those things are obscure and not notable and people don't really care.
Things which are notable tend to require developed skill and discipline to get good at it.
Of course you will be better than most people at it and most people suck at it if you put discipline towards developing a skill. For example, fencing, drawing, playing an instrument, rock climbing, a sports club, a martial art. And such hobbies are notable in my opinion and make you more interesting.
Chad in high school being QB at football, yeah, he might have been naturally more prone to muscle gain and discipline such that he could do something others couldn't, but it still takes effort and discipline to even get to that point. Did high school football players not lift and not die in practice?
