Always drive the head into your opponent on a takedown, never walk around with your butt up. The best time to move again is right after a successful move. Practicing even once a week off season puts you way ahead of those who only practice during the season. Wrestling has many styles, each emphasizing different techniques to accomplish the same objective. Fight to the very end, never quit, especially if your opponent is stalling.
Conditioning is a personal responsibility.
You only get out of wrestling what you put in. Never admit you lost, only that you had a bad day and things will get better. Everyone draws a terrible referee occasionally and not much can be done about it. Don't expect sympathy when you get hurt, especially in high level matches. Sympathy makes it hurt more and prevents you from concentrating on getting the job done.
