When to call it quits?

Right, I'll change the question slightly: When should you realize that you're just bad at chess?

If you asked even a lot of titled players they'd say they're bad at chess. I find most chess players think that the range where "bad" turns to "good/strong" is usually about 100-150 points above whatever they are rated lol

Humans in general are bad at chess unfortunately

you only realize you reek AFTER you've played enough games, studied some, done puzzles, watched videos... if you're sick of it, maybe you should just walk away from it. people do. they usually do fine................. on the other side, there are chess burnouts, guys who just kind of hang on....... i don't think anyone has walked away and suffered dire straits.......
