Parents - If you have trouble staying positive or poised during a game…
• Move further away from the field or court
• Go to a game where you have no emotional ties and just watch… How are the refs? How is the coaching?
• Discipline yourself to do the same thing that athletes are being taught. Stay in control. Be the face your team needs to see. If we expect our young athletes to be poised and confident through all the ups and downs of competition then the adults need to model poise and confidence.
