Hi there, what are some techniques you guys use to stay calm under pressure? Specifically when you need to stay focused in a high energy, possibly physical situation. Strangely enough, i am a boxer, but for the life of me, when i'm in a group, and not "allowed" to fight back, i begin to struggle. Tough phhysically, but mentally i lack a bit.

By not cracking, i mean being able to perform the task at hand. I usually just remain emotionless, but if i still cant do what i need to do, i'm cooked.

I can whoop plenty of ass, but thats not an option in everyday life.
