In this thread the vast majority of people pointed to ego as one of the attributes of their worst instructor. That got me to thinking... just how important is ego in the martial arts or in life in general? Too large an ego and you become an overbearing ***. Too small an ego and you just never develop that sense of self esteem that is necessary for success. My question to all of you is how important do you think ego is in your life? Not just the martial arts but your relationships, jobs and so on.
