It's going to be difficult

It's the new year and you've decided you'd like to try Jiu Jitsu. Awesome! It's almost a guarantee that you'll be terrible, or at least you'll feel like you are, and that's okay. Sometimes it's good to not be good at something. The only activities that adequately prepare you for the difficulties of grappling are other forms of grappling. No matter how good you are at cross fit, stick and ball sports, track and field, or striking, when you start BJJ, you'll feel like an infant. That's not always an easy thing for people. The attraction as well as the frustration of grappling is its complexity. It is not absolute, it is incredibly physically demanding, it's constantly evolving, and it is more effective in a meditative flow state than when you're thinking about it. From no prior knowledge to basic competency by most standards takes years of putting in multiple days a week, and there's usually a period where you're not having much success in implementing what you learn. That's standard, and whether you take 6 months of basics classes without rolling, or jump into the fire of rolling your first day, struggle is part of the process. So as hard as it is, there is just a certain amount of faith in the process necessary to thrive in jiu jitsu, your coaches got where they are somehow and they want your success. In fact most of them are trying to make it easier on you than it was for them if you can believe it.
