My reading slowed down when I joined the workforce too, but I've been able to keep up a rate of 10-15 books a year by making sure I have designated reading time and always a book ready to go. For me, that's while I'm eating breakfast and lunch, when I'm on a long car trip and not driving. I alternate fiction and non-fiction, fluff and educational books, and have no hesitation about putting down a book that's boring or feels repetitive. The biggest factor in making in fun, for me, is eliminating guilt from the equation. So I don't schedule it or set goals, I just leave room and opportunity for it.
