You should read that book. Seriously. If you don't have fun at your job, and you're not having fun away from your job something needs to change. It's easier to have fun in the latter situation versus changing your job. Good luck my friend.
If not, I recommend "Timeline" by Michael Crichton. It's not a taxing or immensely intellectual read, but it's a great adventure story with very interesting and suspenseful parts. It's a lot of fun to read and definitely won't feel like work - it'll feel like play.
