#2 Consistently practice what you preach
Be a consistent example for your athletes of the behaviors you suggest.

#3 Be aware of your nonverbal behavior
Make sure your non-verbal signals don't contradict your verbal behavior (e.g., don't give positive verbal reinforcement with a negative tone of voice or a stern look).

#4 Instruct, don't just state the obvious
When a mistake is made, don't end the communication with what was wrong.  Give specific instruction on how not to make the mistake again and close with a supportive behavior.

#5 Sandwich criticism
Begin and end your comment with something positive, then give the correcting or scolding comment, and end with a supportive comment.

#6 Be consistent
Don't exhibit negative behavior one day (perhaps after a loss) and positive behavior in the next.  Become and remain a consistently positive role model.

#7 Treat athletes with equality in mind
Be consistent regarding where your behavior is directed.  For example, treat all athletes equally and support all athletes equally.

#8 Eliminate dead time
Avoid drills and activities that leave participants standing around.  This causes boredom, lack of enthusiasm and may cause discipline problems.  Most importantly, athletes need all available time to keep learning.

#9 Be realistic with team and individual expectations
Having overly difficult goals may set the athletes up for failure, while easy goals set them up for complacency.  Set goal that are challenging but achievable.

#10 Use "Do" commands rather than "Don't" commands
By using a "don't" command, we place that picture in an athlete's head (ex. don't keep your legs so straight).  Be sure to explain the corrective behavior with a "do" command (ex. bend your knees).  Knowing what not to do is not enough -- explain specifically what to do instead.
