This is from one of my newest favorite blogs called Indexed. Every weekday the author posts a picture of an index card with a graph or chart that represents a way that she makes sense of things. Some are quite funny, and some, like this one, are simply right. If you have time to kill (really? you have time to kill? who are you?) take a look around.
Thanks, Indexed, for the quick sprinkle of morning sanity on my Cheerios each day.
