People sometimes do things because they enjoy doing them, even if they aren’t particularly good at them.

Who are you, to define what "the thing" is, for someone else?

Doing the thing isn't about judging other people. That doesn't contribute to your thing.

If someone is bothering you, making it hard to do your thing, then your thing involves talking to them about your problem. Without judging what they are doing.

Well you are pretty bad at comments. Hang up the keyboard bud

Oh.. So you start doing something new and you're top 10% without practicing or being bad at it first? I'd love to test that to see if it's the case... Your logic is "You're not the best ever to do something so you are not doing it" means you have probably never done a single thing your entire life. Maybe you should just stop.

Yeah the dude should have stopped doing what he liked

no, theres a different thing here, which is that practice needs yo be deliberate.

the answer isnt to stop practicing, its to practice the right thing and not practice doing it wrong.

theyre probably still better off playing badly and enjoying it, vs just staring at an unplayed piano though

Maybe people did tell him he sucked, but he was having fun

Just let people be.
