I recently posted this "Letter to a New White Belt" on my blog and thought it might be helpful to the TS since he asked about etiquette:
Dear new white belt,
Welcome to the wonderful world of Brazilian Jiu Jitsu. I hope you stay on your jiu jitsu journey for years, become truly good at Jiu Jitsu, make life long friends, and find a fun way to stay fit.
You may find that your first three to six months are the toughest period of your Jiu Jitsu journey. In order to reap the benefits of BJJ, however, you must make it past this initial stage. For this reason, I wanted to give you some advice on how to make it past your first six months:
Pay attention
Your instructor will likely show you a few basic techniques in each class. Pay close attention to these techniques because you need to learn them.
Drilling is better than training
While live sparring is important to learning a technique, drilling a technique with little or partial resistance is more important. You may use a bump-and-roll three times in a five minute training session, but drilling a bump and roll 30 times in five minutes is better for you.
Relax
When you do train - relax. Tensing up is a fight or flight reaction, and you can’t use technique effectively when in fight or flight mode. Many folks just starting BJJ need indicators that they are tense, and the best one is your ability to breath. If you’re feeling out of breath it’s likely because you’re tense.
Muscle is finite; BJJ is infinite
You will undoubtedly train with other white belts who are smaller and weaker than you, and you will be tempted to smash them with strength. But don’t. If you rely on technique - and only on technique with smaller people - you will be able to use technique against folks your own size as well.
Use what you’ve learned
Try to use the Technique of the Day (TOD) when you train. My greatest failing has been not trying the technique taught that day, and my Jiu Jitsu game is the worse for it.
Use only what you’ve learned
If it’s your first class and all you’ve learned is a bump and roll, than just use a bump and roll (and some reasonable amount of choke defense). Please, please, please don’t try to use some technique you’ve seen on YouTube or UFC PPVs if you haven’t been taught the technique at your gym. Once you’ve completed your first year and have a general sense of the basic techniques, then DVD and YouTube instructionals may be useful. Until then, however, stick to what you’ve been taught.
Prepare to be challenged:
Unless you were a hard core athlete in school, Jiu Jitsu will push your body harder and take it farther than you ever thought possible. This great sport will also challenge you mentally and emotionally. You will experience times of doubts, but life (and Jiu Jitsu) is about breaking past the doubt.
Tap
Everyone says this, but be prepared to tap early and often. I could have avoided many stupid injuries if I had been willing to tap, and I would be better at Jiu Jitsu today because I would have spent more time on the mat.
Avoid injuries
Every injury you avoid means additional weeks or months on the mat. So tap early, tap often. Stretch. Call it quits when you just can’t go any further. In other words: use common sense. See “Tap” above.
Be a good training partner
Practice good hygiene, trim your nails, don’t train while sick or with a skin infection. And, most importantly, don’t use illegal techniques (Yes, Virginia, slams, neck cranks, and many other techniques are illegal).
Avoid infections
Skin infections (especially ringworm and staph) will sideline you for weeks or even months. Shower after practice; wash your gi; wear flip flops when you walk off the mat and especially in the restroom or lockeroom. See “Be a good training partner” above.
Embarrassment is fickle
You won’t embarrass yourself by asking how to tie your belt; asking to see a technique again; being tapped by a woman; or asking a higher belt how she tapped you.
You will embarrass yourself if you walk in and say “I want to be a UFC Fighter”; show all the higher belts your cool new technique from Youtube; or talk incessantly during class.
If you make it through your first six months, then you could be the future of BJJ. I hope you have a long and successful Jiu Jitsu journey with only a few injuries. I hope you become truly righteous at Jiu Jitsu and go on to win national and international championships.
