I love this book. Anything done by Tim Ferris is fantastic. He's now written 5 books I believe:
I enjoyed this book immensely because I feel like I'm learning the best advice in the world to become healthier, happier, and more successful. Though it's long (650+ pages), every piece insightful, useful, and applicable in some manner. Chapters are short and straight to the point, making it an easy read. You can skip chapters that revolve around a topic you don't care for or an individual you don't think you have anything to learn from (though this would be a mistake in my opinion).
There is so much great information in this book, I highly recommend it!
Next on my list, Tribe of Mentors. Time to reread it. :)
