Spirit.

My shins are bruised.
My knees feel loose in their sockets.
I think I over-extended my left ankle; it's sending sharp pain up my leg with every step.
With every exhale, my ribs creak in suspension.
Inhaling air makes me dizzier. I feel the oxygen molecules in my brain flare up like swirling glitter in a glass snowglobe.
My forearm has a knot on it, tender to the touch.
My face feels hot on one side. Hot from the inside out.
My lower back is strained. The right side of my neck is taut like a steel cable on a winch.
My eyes are clouded with tears. They sting with sweat. Blurry apparitions dance in front of me, barely out of reach.

With every kick my ego shatters into more pieces.

I am building the Taekwon-do spirit.
