I, too, have books everywhere but wet areas.

I find books so hard to clear because they aren't an investment in now, they are an investment in a time that I will have at some point in the future. I can't read them as fast as I'm buying them, but I have an expectation that my rate of reading will far outstrip my purchasing power at some point, and so many of these books won't be available, because they spend so little time available these days.
