Re: What is holding you back?
Personally I just don't like a lot of noise or to make a lot of noise. It calls attention to me so I figgured I would be likely to kiai a whole lot. But looking back there have been times when I have done so in intense work situations where I needed to break through to a higher level of intensity. It generally causes a large pause in the activity levels around me.
My last class at the dojo was the first time we actually worked on it as a part of our class and the self conscious calling attention concerns kicked in but I have no doubt that when the time comes I need to hit a higher level of intensity on my technique I'll find it happening all on its own.
