A few years ago, Dr. Allen Fox made some useful observations about tennis and emotional control. His advice has a lot of carryover to martial endeavors:
"In a match, it's very necessary to maintain emotional control. By 'emotional control' I mean two things:
"One is, you don't have anger or discouragement or these emotions that hurt you.
And number two, you create emotions that are helpful to you, like aggression, and excitement, and optimism.
Now with most people, their emotions tend to follow what's happening on the court. If they're playing badly, their emotions go down, and their game tends to follow.
"The great players don't let their emotions be determined by what's happening on the court – they use it, but they're trying to create the emotions themselves.
Maintaining emotional control is one of the keys to winning tennis matches."
What Dr. Fox says about tennis is just as applicable to winning the gunfight.
