I played a video game called Halo 2, and getting the rank of 50 was a prestigious thing back then. Few people had it and it was based on the combination of skill, games won, and time spent.
I made it my goal and mission to get to the rank, I only friended top players, wouldn't play with friends who just wanted to have fun playing and weren't the greatest... I worked at improving and ranking up and what do you know I finally got to 50 after 6 months of playing everyday. Only about 5% of players were that rank.
What I realized once I got there was what a huge waste of time it was... I wasn't playing the game for the right reasons. I wasn't even enjoying myself when playing. All I wanted to do was win and get to the next rank.. 45 down let's not get put back to 44 with losses but get to 46. Once I was at 50 it was cool for about 10 seconds.
I learned a lot from that. Enjoy the journey, not the result.
don't concern yourself with who is what rank and how they shouldn't be that high, and you should be higher. I used to think like that but it gets no one anywhere, and just focus on yourself.
So as for your original point for the belt promotion. I would say work hard, go in with the attitude of if you get it that's great, if not find out what you need to work on and have fun with the whole process of it
