I think some skills should be learnt from very early on, like skiing or swimming could be leant from toddler age, at amateur level, and then maybe when they are teens they could study some skills at competitive level, and once they reach young adult age, they could practice it at professional level. So there will be three levels of skilling, each with intermediate skill levels and most importantly benefits. Competitive level skills will require more skill practice and might bring some competitions to win and prizes, and professional level might open up a career option or some extra job perks, and less chance of failure, and will require daily practice to keep up. Like if my level 10 cooking sim cooks all dishes in the catalogue at least once at excellent quality he gets to call himself a chef and can open and cook in his restaurant, maybe gets to unlock some extra recipes too. There should be a difference between such a sim and one who cooks the same salad dish every day. Basically I would like more steps to skilling up and more perks, I play with aging off and sims eventually reach top levels whether I want it or not. Also there should be no skill increase for poorly done stuff and skill level should also decrease if not practiced for some time.
