In my dojang competiting in a tourney is required to advance to Black, but irrespective of that requirement, I wanted to compete in tournaments since I started my TKD training. I think it's gives one a positive experience and, yes it does let one confront any fears or anxieties one has about going one to one against another practitioner.
Tournaments are usually an all day thing, from the early morning check in, through the poomse competition and finally to the kyorugi scrapping competition that starts in the afternoon and goes to the evening. Just the heavy training and preparation leading to a tourney is hard but it's very rewarding after it's all over. The adrenaline I get from competiting in TKD tournaments is so great. To compete in front of a crowd of strangers, family and friends is a reward in itself. I used to play high school football, and the adrenaline high I used to get then, playing in front of crowds, getting ready to pound and get pounded by opponents hasn't been matched for me until I started competing in tourneys. And I was just a high school athlete. MA tournaments are a cool experience for any martial artist... :asian:
