A Cleaner feels burnout like everyone else, but the idea of walking away and not thinking about what he walked away from creates more anxiety and stress than keeping it going; that addiction is still demanding to be fed. That’s why you see guys retire and return; they’re still not satisfied, and they still have something to prove. Not to you, but to themselves. The pressure is all internal. You have to crave that pressure, embrace it, and never let up. You don’t have to love it. You just have to be insatiable for the results.
