And here's another unexpected benefit: making time for the important things (including books!) has meant that I spend less of my valuable spare time on work that I bring home from the office. On many an evening, I used to flip open the laptop in front of the TV and catch up on e-mail, work-related reading, or other tasks. The problem is, the work never ends. I could do that every night and never feel truly caught up.
So I am finding the 50 books goal to be motivating in many ways. Without it, I would still read several books, but probably not so many. Because of the goal, I make a conscious effort to make time for reading and prioritize that above work and time-wasters (do I really need to watch that "Seinfeld" episode again?).
Overall this is proving to be a very satisfying journey and a wonderful way to keep work and life in balance.
