Omg that is so great. A) giving them a wide variety of choices makes it seem like a hobby rather than a chore; B) they're so young that once they get used to the regularity/habit, they'll learn to love it on their own; and c) I assume that you mean if they don't complete the season they'll have to start from scratch the next year - worst case they regret their decision, but 90% of the time active kids want to continue in sports, so they'd migrate to another. Best case they become addicted and become regular little shitlords! :)
