To each his own, the imporant piece in my opinion is to not judge others by your own measuring stick or live your life trying to measure up to others to get their acceptance or approval.
Every runner practices and runs to win the race. Every fighter also fights to win a championship. I realize a job isn't any of those but when you realize that ultimately a runner and a fighter both run and fight against themsleves, to be the best they can be and nothing more then maybe that is something we can all relate with.
