Are Me Smrter?

You know, it's weird...there's a section of my economics book that I've read at least three or four times over the past couple months, and every time, I ended up still not understanding it. However, after reading through it again a few minutes ago, it just started to make sense and seem fairly simple, as if I never had any problems with it in the first place.

Stupid brain. Where were you in April?
