When I was a white belt and blue belt, I competed a lot, since I was single and younger. For the past 5 years, it has calm down a lot, since I'm married with children and I'm older now being in the Master II division (36 - 40 years old). The mindset is different as well, since I'm calmer and my objective is a bit different, depending on the competition.
So when I was a white belt and blue belt, I was going to competitions to win everything, but now I go to the smaller tournaments to test some things and I go to the bigger tournaments for the win. When I competed a lot, I took every loss personally, and now I'm just grateful to be healthy enough to compete and if I win, it's even sweeter, since I know that I'm barely training in Jiu Jitsu.
I have a ton of competition experience, so I don't get too excited going to tournaments. Going to tournaments is more like a reunion for me to see all of my Jiu Jitsu friends and family. I get to hang out a bit. It's nice because I never hang out after lunch Jiu Jitsu and chatting online is not the same experience as with being with people in person.
I'm pretty selective now with the tournaments, since I'm experience with my current rank. Even when I get to brown and black, I'll still treat the tournaments the same way. My tip for the inexperience tournament grapplers is to be conditioned, relax, and stay with the techniques that they know. If your coaches are with you, LISTEN!!! Just make sure to pay attention to what you are doing in your match.
From experience, when a coach yells something that I don't know, I lost concentration, lost position, and lost my match. I was kind of surprise that my coach got mad at me during that time, because I was barely doing Jiu Jitsu for 3 months and I was in on my 2nd tournament. I think coaches need to be compassionate and understanding of each student's situation. I wouldn't expect too much from a white belt, since they are barely learning the moves and the name of the moves. Well, I'll note more on this journey next week. Good day and thanks for reading.
