Ever expanding shelf (One book per month) (Score 1)

In my experience, it is fairly common for good software developers (working in industry), to read no less than one book per month. What you need to remember (and what other posts have already emphasized) is that these books shouldn't only include "flavour of the day" books on particular languages or tools; they need to include the broader stuff, those things that stretch your understanding and make you a better problem solver.
