When a person does not think, "Where shall I put it?" the mind will extend throughout the entire body and move to any place at all. . . . The effort not to stop the mind in just one place - this is discipline. Not stopping the mind is object and essence. Put it nowhere and it will be everywhere. Even in moving the mind outside the body, if it is sent in one direction, it will be lacking in nine others. If the mind is not restricted to just one direction, it will be in all ten.

Takuan Soho (1573 - ?) 

I try to remember this quote, because it is representative of what I should be doing in all my endeavors. We tend to get bogged down in the details of getting something done, to the point that meeting the goal becomes replaced with some other objective - like being clever or elegant, for instance. In the martial arts, it might result in your style losing its martial effectiveness and prioritizing looking good instead. In daily life, it might mean closing ourselves off to other possibilities that might make us better off.

Don't get taken up with any one thing, so you can accomplish many amazing things.

In the video, Ken (the male character) was reduced to just one bar of life - that means any attack could have knocked him out. There were only thirty seconds to the timer at that point, and this was a deciding match for the championship; the move that Chun Li did near the end usually would have sealed the deal - it hits multiple times and the defending player only has less than a split second to decide whether a hit needed to be blocked high or low. Most players would try their best not to get into this situation and would concede that this is pretty much "impossible" to get out of. But the player behind Ken, Daigo Umehara, proceeded to parry all the hits under incredible pressure before going into a combo of his own, stealing the second place title in a miraculous comeback.

My teacher's teacher always answered in response to the question of how to fight multiple opponents in this way: "One at a time." No advice about keeping a concealed weapon, or even anything about special techniques. More and more now I am beginning to take him at his word. :)
