1) go back to college
2) major in arts or humanities or something like that.
3) hang out at Starbucks a lot.
4) wear a beanie even when it is 100 degrees outside.
5) only listen to super underground indie music... when other people discover these bands, talk about how they sold out and how you only like non-mainstream stuff.
6) become a vegan and go non-gluten
7) be really judgy about other people's choices in music/art - (this is key... people will only see you as cultured if you act like your views on music and art are the only ones that matter)

BOOM... you're welcome.
