Being a well-rounded grappler should be the aim of any BJJ practitioner. The idea of being well-rounded is easy enough to understand and agree with, but the method of achieving it is another matter entirely. This is where many fall short.
To be “well-rounded” means having at minimum a sufficient competency in ALL aspects of Jiu Jitsu, not just the ones where we naturally veer toward. If we avoid the aspects of BJJ we are uncomfortable or vulnerable with, we lose the opportunities to improve. We will stagnate in our “comfort-zone” while those who are engaging their fears will flourish.
If growth and improvement of our skills is the goal, and we want to become well-rounded, we need to branch away from our default modes of rolling. We need to become exposed to those situations and positions which we are unfamiliar or uncomfortable with. We must go fearlessly into uncharted territory to broaden or horizons. This means we need to accept some risk. And the dojo is the perfect place to do that. With training partners who have your developmental interests and protection in mind. The worst that can happen is you fail. You get swept, submitted or your partner gains positional advantage. Who cares? Every so-called “failure” is just another opportunity to learn. If you attempt a guard pass you don’t normally do (i.e. are uncomfortable with) and get swept, you immediately gain knowledge. The “failure” is immediately error-correcting! Being swept is a great price to pay for knowledge.
People who are adverse to taking risks usually don’t see the reward of messing up and also don’t want to look bad (or dumb). To varying degrees, risk-adverse people are short-sighted and ego driven. This hinders skill development in BJJ.
My recommendation: Put yourself out there. Try movements and positions you are unfamiliar or uncomfortable with. Expose yourself to every little hidden corner of Jiu Jitsu. Take risks without fear of messing up. If you hate being mounted, get mounted. If you only like top position and avoid bottom at all cost, start off your back and earn your way to the top. If you hate standing guard passes, do it anyway. The reward is worth it. Stop being so conservative. Remember, risk can trigger flow. So, broaden your world and take a risk.
