Diversify

I am not a fan of specialization in grappling. I think that the goal should always be to become as well rounded as possible in your discipline. There will always be things you are better at and things you gravitate towards, but you should be able to execute a broad spectrum of skills and demonstrate that you have that proficiency. It is difficult to practice areas of weakness when rolling begins neutral, so that it is better for either you or your coach to set parameters on most of your live training. It is also good to enter competitions and take classes that are adjacent to what you do. If you do BJJ then entering a judo or wrestling tournament or taking a class will benefit you even if you have no plans for great success in those arenas. Grow your skill set always and don't stay stuck in the same patterns.
