Practice is the easy part
We're talking about players who go out and train with the track team so they can learn to run faster. Who run until they puke, catch a short rest, and start running again. We're talking about the kid who finds and follows a sport specific lifting program every day after school during the "off season" whether or not any of his friends and teammates do it with him.
We're talking about players who will drive 2 hours each way so they can spend 1 hour training with a top instructor, and then take ownership for working every day on the skills and drills in which they have been coached. We're talking about the player who takes a pass on hanging out at the mall, or going to a party, because he would rather do his homework, training & skills practice ... because that is what will get him where HE wants to go.
Then, we're talking about the kid who is the first to practice, and the last to leave. The kid who gives the best he has every rep of every day, because he loves what he is doing, and he passionately wants to become the best he can become. He shows up in a clean uni, shirt tucked in, cap on straight, all the gear he'll need, because he respects the game, his team, and himself.
We're talking about the kid who seeks out the best competition he can find, because he would rather risk losing to the best, than look great beating the weak. We're talking about the kid who when he suffers a set back, or when others don't believe in him, he presses on, and pushes through because he has learned that temporary defeat is a key part of achieving success; and he believes in himslef, and his dreams, and he isn't going to stop until he has given everything inside of him to transform his dreams into reality.
That's the type of player I'm talking about. I, for one, think that one of the most valuable things we can do for our kids as parents and coaches is to teach every kid to pursue whatever it is they are passionate about with this same level of passion and drive. Whether or not they grab the gold ring (no brass here), is less important than learning to give 100% of themselves towards the achievement of a worthwhile goal.
My 2 cents.
