I've been thinking lately that my brain is a little like a computer with a single-core processor and a tiny hard drive that I try to use like a multi-core processor with a big hard drive. At least I have a lot of random access memory.
I made the following diagram ("I make a lot of graphs"), to illustrate what my brain would be like if it were a computer. This is of course just what it looks like when I'm sitting around drinking coffee or not paying attention in class. When I have other tasks... well that's when I start getting error messages and freezing up.
