Never take yourself, or your game, too seriously. If a sport isn't fun, it's no longer sport. The quieter you speak to children, the louder they hear you. Kids should look forward as much to practice as to games. Practice should mean more ice time, more fun and more improvement.
Games are when practices show up.
A pat on the back has never been known to injure a player. We learn from our mistakes, and if we make players too afraid to make mistakes, they will stop trying to learn. Games are not jobs. If you can't laugh at yourself, rest assured others are laughing at you. No coach should have to put up with more than one Nishikawas per lifetime.
