Query: Great read - thought provoking!

This book was recommended to me by a business colleague and I bought it to be able to tell him that I'd read it. Boy, was he right on! This is a great book for our times - helps us be forward thinking about our real purpose, being authentic, and the impact of our decisions. Quality of life should not to be taken lightly. I'm going to gift this to our 3 sons for their birthdays this year!
