Pain is a tool for those that toil in their trade. Some do it for the rush that fills their very fiber. While others use it to push themselves forward, over the crest of that mountain.
The tool? Pain. Use it wisely. A quick snap of the wrist here elicits the desired movement of your attacker. A simple push of the finger at the right spot behind the ear and pain shoots right through their head. This tool is multifaceted and double edge.
Ignoring it could also lead to disaster. You decide to execute a simple move, your foot gets stuck in their hip joint. Pain starts to build on your ankle. Ignore it. It's just pain. POP! Did I just misuse the tool?
