Agreed, I have older daughter, she enjoys lacrosse, is very good, but she'd rather go hang out with friends, go to the mall, go on friends boat, etc then go in backyard and lax train in August.

Having her skip these normal teenage things is a recipe for resentment, both resenting you and the sport.

Here's another fact based on reality, there's some kids who can train 24/7 and just won't be elite, and others who can only do it a few times a week and be studs. Some things aren't taught or mastered with work.
