Good players win volleyball games for you, not tall players.
There is nothing less important in life than the score after one game of a two out of three game match.
Alter strategies and tactics, but never your principles.
A coach must sometimes see players with his heart, and hear them with his eyes.
Make your mistakes with confidence. It is the only way you are going to learn anything. Never be afraid to do a skill, no matter how simple or hard it may seem someone has done it, and so can you, With enough committed practice and confidence.
You must allow your players to become the athletes they can be. Don't make them into anything just to become the kind of winners fans, friends and others think they must be.
