I believe the objective of coaching is winning with integrity.
If you think you are working hard, you can work harder. If you think you are doing enough, there is more that you can do. No one really ever exhausts his full potential.
A coach's job is to put his team where it can function effectively and win.
Coaches win practices, players win games
In a team sport like basketball, every time you help somebody else, you help yourself.
A player's ability to rebound is inversely proportional to the distance between where he was born and the nearest railroad tracks. The greater distance you live from the poor side of the railroad tracks, the less likely that you will be a good rebounder.
