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.
I used to work very long hours. Then I started to realize that the stuff that I was writing in the late afternoons, I was generally throwing out. So I quit earlier than I used to.
