Keeping your cool

Probably one of the most important skills a martial artist develops is to keep their cool under pressure

If you get angry, shocked or overly excited the adrenaline shuts down many of your skills

You can be the best practitioner in the world but if you're unable to keep your cool and easily wound up then you have a key opening. It has a lot to do with ego, self awareness and practice/training

I wonder how people can think of themselves as martial artists if they can't even keep their cool during debates on an online forum?
