This is not really a book - but that doesn't make it bad. Just know what it is. It is a publication of Gallup research in a very concise format. “Chapters” are 2-3 pages at most. It covers the “what” and “why” but not so much on the “how.”
A third of the book is the documentation of the studies, that while very thorough, I doubt anyone will read unless research papers and academic journals are your thing. The last third of the book is dedicated to Clifton Strengths. Again not a bad thing just not really a book.
Also, not being able to get an e-book in the format of my choice is a downside. The only e-book format is for Kindle and it costs (currently) almost twice as much as the physical copy.
