Oh man, it's tough to answer this one well. I just counted up the books I've worked through on my shelf. After college, I've gone through about 15 completely, and partially worked through another 15 or so. Plus a couple reference texts that have been handy. Plus a huge number of papers. They take up nearly twice the space my old college texts do, which is kind of wild to look back on!

Are you curious about anything in particular? Or if you're just wondering what kind of books I'm talking about, highlights include CLRS, Probabilistic Graphical Models, Mostly Harmless Econometrics, and Characters & Viewpoint. Next up on my list are more creative writing books and a couple theoretical stats books (I'm working towards a book on semiparametrics, but first need a better foundation to follow a book I've been recommended).
