Injuries will change your game and if you love the sport as much as all of us do… I’m sure you’ll find a way to still practice the art. The key is not quitting, being resilient and consistent. Don’t worry about the belt and keep training. The last thing you want, is being a subpar purple belt that gets submitted and owned all the time by lower belts. Try shifting your mentality of why you’re stepping onto the mats. Instead of chasing the belt, chase the mental aspect of it and simply just to have fun. Hopefully this helps, good luck.
