While I think on the whole value concept, I do want to pass on one of my favorite books right now: The 4-Hour work Week: Escape 9-5, Live Anywhere, and Join the New Rich by Timothy Ferriss. This book isn't about working less, it's about working smart! And living the way you choose to live, whether it's traveling or spending more time on worthwhile activities. Just the chapters on The End of Time Management or The Low-Information Diet will get people rethinking their way of getting stuff done.
Ferriss has a great web site, Experiments in Lifestyle Design, that is filled with ideas such as creating a paperless office - check it out at How to do the impossible: create a paperless life and never check voicemail again.
