In the pilot of Girls, Lena Dunham's Hannah Horvath delivers one of the 2012 fall TV season's immortal lines. She can't hang out with her parents, she explains exasperatedly, because "I have work, and then I have a dinner thing, and then I am busy - trying to become who I am." Memory research supports this notion that our twentysomething years are gardens of self-creation (or ramen noodle cups full of self-creation, if we're honest). No wonder the decade is so, well, memorable.
