I got this book to enrich my insights on some leadership skills that I elaborated during my master’s program. It was meant in one of my primary literatures, so I went ahead to read it. I mean what resembles transformational evolution better than a butterfly... :) it is surely useful for the ones looking for practical tools and approaches in defining priorities and focus in life. I gave it 3 stars as it has not served the purpose in my case in conjunction with my inquiry. So it is a very subjective review...
