Getting 'Mad'

Tonight I got 'mad' at my high school team, making layups and doing things right is not always easy for kids from 15-17... I wish they could understand the importance of listening and understanding what is being taught. I know that repatition is part of coaching, repeating the same things over and over is a large factor in winning or loosing for the long run, I at least know that the kids know where I am coming from and that's a huge step as it is. Nothing wrong with me showing my emotions at practice, but the funny thing is that when I did get mad and made them run for missing easy layups and threatened them again with running if it continued... What do you think happened? That's right, no more misses - I ask them why and someone says concentration, YA... and then I said to them, just think if you all could concentrate for the whole practice, think how much better they would be, and so much faster.... Listening is a very improtant part of getting better as a hoopster, even I will admit that... I would say that getting better at anything, including life, is based in large degree in how we listen and learn. Havin g to learn form ones mistakes is ok, but I what a difference it would make if one could really learn from just listening and taking the possiblity for creating a better self seriously?? Babbling on here I know.. gottsta go da..
