I would recommend you to leave the pressure aside, I know that you came from a long trip, and you want to win because you have been training hard, but the most important thing is to enjoy. Enjoy the moment, the tournament, the fighting, because even if you win or lose you´re going to bring with you a very good experience and this is the most important thing. If you are going to compite for the first time, well, take It like that, a first experience to know what is to roll jiu-jitsu with a guy
to a 100%, where you are going to prove yourself to a 100%. If they are White
belts and they lose, dont worry about that, nothing happens, there are even world champions that have never win nothing until the top of their career, is a very long way. Champions are made in the academy, not in the competition, so you have to have a very sacrificed spirit, train hard every day, listen
to your coach/es, have a healthy diet, and..I think that do not give up, always look for
the best.
To be a champion, from my point of view, you have to spend more hours in the mat, the same as a pilot, to be a good pilot and do international
flights, you have to have more flying hours. It can not be to train today and do not train
tomorrow. Is better to train one hour per day, and to arrive one point to reach the
position that you most like, or even the position that your coach teaches to you.
In order to
make your life a Jiu-Jitsu training manual. my point of view to a fighter is the discipline inside the mat, to know that you will never manage to reach any point on your own, because you need your team mates, you need your favourite positions, and you need the variation of your game in order to distract your oponent..
