Yes sir, that is my lovely lovely moleskine. Yes ma’am, that is indeed a binder-clip pen holder.
The moleskine is effortlessly classy, slightly pretentious and absolutely necessary. It keeps me sane. It gets me to do things. It makes me almost feel like a math genius — almost. (I say that because I do in fact know of two math geniuses who carry around moleskines to sketch the mathematical equivalent of doodling.)
