The 4-Hour Workweek by Timothy Ferriss
7 out of 10

Do you want the liberty to enjoy your life the way you want?  Are you tired of "Work for work sake"?  Do you want to read this book?  I'd say it's pretty good.  While I prefer books with expansive research and scientific conclusions, I appreciate Ferriss's mindset.  He lays out his own experiences and prescribes solid methods--such as automating and delegating repetitive tasks--for becoming more productive.  Some of the specific tactics are outdated, but the general principles are legit for achieving more hyper-productivity and self-determination.
