I grew up playing sports.  The sports of choice were:

Basketball
Soccer
Baseball
Track

My school did not have football or hockey (darn).

I am now working with athletes and I have notice some differences from when I played sport to now.  I can list all the differences but I think I want to stick with one issue.  The issue of commitment!  I have seen some athletes just quit a sport in the middle of the season.  In my day that was never heard of.  I'm not sure why some young athlete quit and I'm not here to judge them on there decisions.
