In general, I spend a lot of time in my own head.
Like all things, there are pros and cons to this nature, but one of the aspects that I try to embrace to its fullest is my strong connection to visualization.
In fact, I get obsessed.
For example, every technique I do in the dojo--physically--I do a minimum of two hundred times in my mind when i'm not on the mats. Even kata, which at times I don't enjoy, plays through my head like an old TV rerun before bed or walking down the sidewalk.
Attackers, I picture endlessly; sparring matches, the same.
I even throw strikes at the heavy bag.... as i sit idly daydreaming at work.
Maybe I'm nuts. Or maybe just borderline.
Perhaps, for me, it's how my nature works.
