I went to art school, I think it helped me a great deal because it taught me who I am.
I had a briefcase at one point, but it was a kind of 1980s New Wave briefcase. It was made of some kind of cardboard and it had metal hinges. It was kind of faux industrial looking, and I used to carry my books in it rather than a backpack. I didn't want to have normal student accoutrements.
