Will Hunting: a lower-class nobody from South Boston, yet inside his mind lay a whole other world that no one could ever begin to understand. He worked in construction, laying brick. He called this an honorable profession because "he was building someone's home".
Will defied the expectations that came with his upbringing; he was a certifiable genius. This was the truth, no exaggerating. He could look at complex mathematical equations or organic chemistry formulas and just... know it. One glance and his mind instantly came up with the correct solution. He compared this, often, to how Beethoven and Mozart could just look at a piano, no former training, and just know how to play it. He would look at things and... know how to play them.
Will kept a quiet life, quiet meaning tight-knit and reserved. In certain places and at certain times, he could be a very loud person, but not an obnoxious one; his loudness contagious in the way laughter was, a very pleasant thing. He had a routine, if one could call it that. He hung around the same three guys, went to the same bars and restaurants, slept with the same girls. He was fine with his life; he was content with what little he had. He was at peace with living in the same under-stimulating environment all the time, even if that wasn't what was best for his genius. He was fine.
