I don't really know this kid, but I see a lot of kid black belts, and she is easily one of the lowest in terms of her skills. She (sort of) knows her black belt forms, but her technique is, at best, adult high green or purple belt level. I have had this discussion with my head instructor, not about this kid but generally about kids who try martial arts for a year, or two and want to quit. Though he has lived in the US most of his life, he is old school Korean and told me he thinks American parents let their kids quit too easily. I told him that as a parent, I disagree. If a kid genuinely shows a talent for TKD, then of course, I would encourage my kid to continue. But if my kid has given it a good effort and he is just flatlining AND WANTS TO QUIT, then why would I encourage him or her to continue to plug away at something he isn't very good at when it is possible there is something he hasn't yet tried that better suits his abilities?
