1). trying to get a job [outside of the ring]. he had to make himself noticable to the guy at the dock or whatever that was so that he could be one of the very few people who were picked

2). feeding the kids. he didn’t want to have to send them and he made a promise to his one son. he had to find some way to overcome that. he even gave his bologna to his cutie of a daughter

3). he had to watch out for his friends and neighbors. like in the scene with the childrens’ birthday party. the fight that was about to take place between the man and his wife. braddock had to overcome his fighting reputation to handle the situation

i really hope that helped! good luck!
