In his podcast, Tim Ferriss has interviewed an impressive amount of business people, top performers, and other interesting men and women.

This book is a summary of those interviews. It contains the best advice and most gripping stories.
Tim has also added a number of smaller sections where he explains his own principles in life.

If you like the podcast because of its content, but don't like it because it's hard to keep focused for over an hour, this is the book you've always wanted. I have made an incredibly large amount of notes for later review. It's going to take some time to process everything.

If you didn't like Tim's previous books because they were a bit all-over-the-place. This book is worse. It is organized by subjects, but even then, it's not something you can read straight in one sitting.
