1) You get to leave your hometown, people you grew up around, potential lifelong friends, and all the places that you're familiar with in order to attend college, potentially get out of poverty and have a life of middle-class "creature comforts" or more. The DOWNSIDE of this is that your family, who never tried to make a better life for themselves, resent you and try to make you miserable all the years of your life, creating tension, aggravation, and emotional poison, eventually leading to a complete falling-out and estrangement.
2) You accept your conditions, that things in life are far beyond your control and that luck is the biggest player in all that we become. You grow indifferent toward your circumstances, never really caring much about anything outside of television shows, burger joints, the movie theater, and the mundane existence of all things that rot in the limits of your town in 'wherever' USA.
You could care less about pursuing an education, a better future, a quality woman with values, or going after things that you only read about as a kid. The Positives here are that you get to stay around your broke family, who are even more ambivalent to life than you are, you keep lifelong friends and have some semblance of a relationship with them as the years go bye.
-You grew up poor, to a convict father and a drugged-out mother
-You have the choice to leave and make a better life, pursuing more than you ever thought possible.
-OR, you have the choice to stay, accept your life but keep your family and friends.
-What do you sacrifice?
