The Power of Full Engagement: Managing Energy, Not Time, Is the Key to High Performance and Personal Renewal by Jim Loehr and Tony Shwartz

I just finished reading this actionable book called "The Power of Full Engagement: Managing Energy, Not Time, Is the Key to High Performance and Personal Renewal" by Jim Loehr and Tom Shwartz. The book is focused on the theme that managing energy, not the time is the key to high performance. To manage the energy the book suggests regular breaks or disengagement from work. The book recommends to take a break on each 90 to 120 minutes of activity. That's it. You've read the entire book. The pages of the book is filled with the description of authors' clients' experience on implementing the suggestions mentioned in the book.
