First, I suggest coaches watch the Gregg Popovich exit interview.
Players create themselves...and often reinvent themselves to adjust. Youth doesn't know the game, relationships on and off the court, and lacks skills. Mostly, coaches fill 'empty vessels'. That evolves with game knowledge, shared experience, skill development, but in the critical ability to develop process and habits.
John Wooden's core from the "Pyramid of Success" isn't accidental tourism.
Coach Popovich's comments on Jonathan Simmons resonate praise of player effort and added value.
1) Do what is required to "have a career." Or as Charles Barkley noted, "have an NBA skill."
2) Develop professionalism. Professionalism is the series of behaviors, habits, and process needed to learn and grow. As Aristotle said, "excellence, then, is not an act, but a habit."
3) Become consistent. Professionals are consistent in their conditioning, study, nutrition, and rest. Performance begins with identity and grows according to process.
4) Be relentless. We cannot grow until our work exceeds our hopes and dreams.
5) Make a difference. Choose excellence. Choose to learn. Choose to be more.
Be as interested in listening as being heard.
