Authors Marci Alboher & Tim Ferriss discuss their
books "One Person/Multiple Careers: A New Model for Work/Life Success" and "The 4-Hour Workweek: Escape 9-5, Live Anywhere, and Join the New Rich," as part of the Authors@Google series. This event took place on May 4, 2007, at Google's Mountain View, CA, headquarters.

Personally, I've read the 4 hour work week and if you believe that you shouldn't have to wait until retirement to start living your life then you would probably enjoy it.
