The attitude to rise above the elite academics, trust fund babies, old money products, rich Asians, and other competition that may pose a threat to your future from a social ladder-competitive standpoint… is also utilizeable to strengthen and improve the physique, health, and well-being of the body and morale (“fighting spirit”).
It is not being a good looker, not being “smart”, or not being “gifted” that defines the superior man of battle. Much of us came out of a vagina as infants with nothing into this world. Bruce Lee was not born a master. Rather, it is the burning desire to becoming something better everyday and the continuous ascention above all relevant competition.
