Once you learn to remain calm under the stressful circumstances of a fight, you will have no trouble remaining calm under the stressful circumstances of life.
Remaining calm in times of desperation makes way for opportunity.
I'm pretty good at remaining calm during an emergency. My house burned down when I was 12, which made me really pragmatic about what needed to be done. But I can be bad in that I compartmentalize a lot of emotions and push them away to deal with them at a later date.
