I guess whatever helps you better understand work you are doing? My reading list at any point is tied to whatever I am doing in my private or professional life. If my boss asks me to help grow the company my reading list will contain a bunch of stuff about company growth. If I have money to invest but no knowledge of investing -- you will see me listening to investing books while cooking, taking walks, commuting or long distance driving. Basically, whenever I face a problem I look around for literature to help me with it. I really hope to have an original problem in my life. Until then I assume that whatever problem I have there is somebody who wrote a solution to it and if I can't find it it is just because I wasn't searching hard enough.
