This may be a surprise to you, but there is much more to life than BJJ.
1. You will overtrain
Your body will become tired and not have enough time and energy to repair itself. Eventually you will get injured, and the layoff will hurt more than if you had just been going half as much (5x/week)
2. You will burnout
What you love will become a chore, and you will hate going. Most likely you will burn completely out and again have a big layoff.
3. You need to focus on other aspects of your life.
Like a Mixed Martial Artist needs to be well rounded, so should be your desire as a person. That much time spent on BJJ, means you aren't spending time on other aspects of your life. Even if you don't have a family, you should have other interests and relationships outside BJJ. Read, educate yourself, take music lessons, join a club, enjoy an outdoor activity, spend time with friends and family outside the dojo.
