When I successfully completed a task that my Gungdo teacher in Heilongjiang, China, assigned me to do: To be able to pull a 40lb draw hunting bow to full draw and hold it there as steady and motionless as a stone while tuning out everything around me, drifting leaves, lightly falling sleet and rain bouncing off my face and running into my eyes, 40 degree early winter wind, the increasing strain and burn of the muscles on my arm that is holding the drawn arrow, and only focusing on the swinging target 20 yards in front of me for 5 minutes straight, then loosing the arrow and nailing the moving cube straight through it's center. I was 11 years old. When that arrow slammed through the cube, the man did not congratulate me or say any words of praise, but only said: "Don't feel excited or happy. That was what you were supposed to do. You just learned the basic fundamentals of a martial art that has 20 tiers built up over 3000 years of development." Had already been shooting for years prior but Gungdo taught me the importance of being focused only on an important task at hand and being able to put aside all distractions and anything occupying my mind that is useless, until the task has been completed. These lessons translate to everything in life off the archery and gun range and translates equally: Weakness is doing or saying anything that produces no results. Only be satisfied with results.
