Being active in sport is a good thing although as you point out there's other ways to socialise and interact. I did some of both, wanted to be active and was encouraged to be. Like @mrbokers I had a nice balance of sport, free time to go on adventures, s hooking and music. It helped me develop.
Team environments are good places to learn though right?
I agree with that. They are good places to learn. I think sometimes too much emphasis is put on sports though. Especially in the public education system.
