If you could go back to the beginning…

To all my seasoned brethren… when you reflect back to the early stages of your journey, what is something you wish you wouldn’t have spent so much time on? A mindset that you now realize held back some progress? A technique or concept you now realize is trash or maybe you were training it wrong for years? Etc… Ego I know is always a big one. Rolling too hard on the regular and/or overtraining. For me I think it’s the mental anguish that can take place when you can’t be on the mat for a while for whatever reason. It’s silly to think you’re gonna slip that much because you have to take time off for an injury or life event. I believe if you’re really about this and are in it for the long haul you will find your way back and so will your skill level. What about you guys?
