Emotions can run amok in a stressful situation.  Those can be useful if you have practiced using them.

Many people think only of anger as a useful emotion in a violent encounter.  The truth is that anger, fear, hope, and love are all useful and should be there.

In a previous blog I mentioned that the ability to turn the emotional intensity up or down is sometimes called "killer instinct".  I offered some thoughts on why that skill is important.  I also mentioned a simple way to train to "turn it down".

Today I will offer a way to train to turn it up.  You can do it with no equipment at all.  

Did you ever see a movie where the good guy is having a tough time, then someone hurts his buddy/wife/child and then he goes berserk and wins out after all?  I hate that.  There is a time to "go berserk" in a fight and there is a time to keep it under control.  If you are in a situation where your loved ones are in danger, you need to keep your head and make good choices.  People who just go crazy tend to do stupid things and get hurt.   That's my problem with movies like that.  If you turn it on at the wrong time, you make things worse.
