Marcelo shares his thoughts on two interrelated points; preparedness and relaxation. He stresses the importance of having trained for a diverse set of positions, both good and bad, that one might encounter during a match. You shouldn't have an incomplete game in the sense that there could be certain unavoidable aspects of a fight wherein you feel uncomfortable or even worse, clueless in tactics or strategy. Explore all parts of your competition game in training before a tournament, both in stand-up (tachiwaza) on the feet and for techniques on the ground (newaza); you don't have to achieve mastery in each of these realms, but you must at the very least know enough about the position to remain calm and focused on a task. The more you accomplish this in training, the easier it will be to conserve your energy before going out to compete. You can rest assured in knowing that you didn't leave any stone unturned, and you aren't going to be surprised with something you haven't seen before. If there are gaps you didn't cover, whether that be takedowns or even survival skills, you may leave room for doubt to creep in and possibly be overcome with anxiety that can spiral out of control, leaving you exhausted even before the match begins. The more you stay relaxed, the more energy you can save and then later spend defeating your opponent.
