I think this is very situational. If the kid has no real interest, there's not much harm in them quitting. If they quit because it gets hard, because they get discouraged, or because they're not good (even though they have interest) that might be more problematic.
In my youth kids were sometimes told "if you start something, you will finish it". What are your thoughts on this ideality?
We were also told we had to finish the season. We made a commitment, and that’s what you have to do. If you really don’t want to play anymore, you don’t have to join next year. But you’re finishing the season the right way. Of course if there were outright justifiable reasons to quit, that’s another story.
But MA doesn’t have seasons. There are milestones. Substitute X belt or end of contract for season here. Hopefully parents are at least holding kids to that instead of just walking away once things get tough.
I find most adults that stay past that initial honeymoon period quit at 2 distinct points - when the actual sparring starts (beyond going slow and getting a feel for it) or shortly after 1st dan.
A few reasons I’ve come up with:
Sparring: it’s no longer cardio karate/kickboxing in a sense. They realize they really don’t want to hit and get hit after all. Not that they’re being hit hard, but just being hit beyond a tap and someone not allowing them to hit them back is unsettling for some.
1st dan: They had a goal in mind and accomplished it. Like checking something off a bucket list. My teacher said he’s had a few people leave right after they made 1st dan, and they told him they achieved what they set out for, so they’re moving on. Some people just want to earn a black belt like it’s a trophy. I don’t get it, but I don’t have to.
Other people lost interest some time back, but convinced themselves to stick with it until black belt and “finish what they started.” Kind of like playing a sport and not enjoying it as much anymore but finishing the season.
Kids like things one day and are bored with them them the next day. Or they’re signed up for something and don’t really want to be there to begin with. Parents talk their kids into things like sports, musical instrument lessons, etc. At some point the kids either want to keep going or want to stop. Quite often they’ll go through the motions for a while to appease the parents before the parents say they’ve done it long enough and can move on.
Not everyone, especially kids, wants to be there in the first place.
Of the group that did truly want to be there, none of them knew exactly what it was going to be like. It’s like meeting a potential mate. You see all this stuff you think is how they are, but after a while you realize it’s what you thought they were and/or wanted them to be like, and not who they really are. Sometimes it works out, but most often it doesn’t.
There’s nothing wrong with setting a goal, accomplishing it, then moving on to the next thing.
