Thinking about a theory that suggests football players see themselves as either "destroyers" (think Marshawn Lynch) or "thrillers" (think Richard Sherman). I had a conversation with a non-BJJ martial artist last year that went along similar lines. He suggested that most people who did martial arts either thought of themselves as "superheroes" (i.e., potential defenders of the weak) or "warriors" (i.e., potential challenge-seekers). Obviously the categories aren't mutually exclusive, but I still think it is interesting to think about. Do you love teaching white belts? Do you prefer training with and competing against the toughest guys and gals around? This may help explain why.
