two boxers are training in the gym.  among them, one of them is training, while the other is looking at himself in the mirror.  these two men are probably preparing for an oncoming fight.  the man who is training probably has less confidence than the man who is looking at himself, so he works harder.  the man who is not working is probably too cocky and assume that he would be victorious.  the man who is currently training will probably win the fight because he has better work ethics than the man who is staring at himself.
