Marcelo plays a coaching trick on his advanced students to help them better understand how to cope with the random constraints, deal with time-limits (or lack thereof), and prepare for the unexpected obstacles that will happen during a fight or in a match: Time is a major factor in how one approaches a way to win a one-on-one contest. If you are in a bad position, but up on points against an opponent in match with little time remaining, you may feel a sense of relief in knowing the clarity and ease of a path towards victory by fighting conservatively and defensively. Conversely, if you are the person who is down on the scoreboard in points and/or advantages, you might feel the pressure of solving the tasks of not only (i) continue surviving, but also (ii) somehow superseding the current circumstances imposed by an opponent. How one deals with adversity on an emotional level will oftentimes determine the pending outcome of a match; handling yourself poorly may rob you of the focus necessary to forestall your opponent and find a way to turn-over the momentum back into a favorable direction. Whenever things don't go your way while competing, whether from something your opponent did, or what the ref saw or didn't see- or even, what you are currently failing to accomplish -you need to retain and sharpen your focus towards making positive and rational choices with your actions. Concentrate on what you can control, and not on what you've already lost. Figuring out a way to set yourself straight when things go awry, and then going on to settle yourself back into a state of lucid and dedicated problem-solving, is a major key to success at the highest levels of competition.
