10 steps for coaches to build good relationships with young players:

1. Encourage dreams but plan carefully, know what you want and keep expectations reasonable.
2. Be the right role model - you are the most important example of the attitudes, standards & behavior that you are teaching.
3. Help players build self-esteem through work & achievement.
4. Make practice challenging productive & enjoyable.
5. Share your knowledge whenever and however possible but be a good listener.
6. Become a good observer of players' behavior.
7. Sell not yell - allow players to take ownership of their own progress.
8. Criticize sensitively and only the performance - never the person.
9. Treat all matches as teaching & learning experiences; don't let your ego get involved.
10. Parents are important to young players - make them part of the solution not the problem.
