I am always on the lookout for advice, articles. books on leadership and management and I have been pleasantly surprised on the scope and quality of the book which is very detailed and of the highest order. The language of the book is simple and concise and the author,Aaron Levy, has bound the book efficiently by starting of in providing a framework to first choose the right mangers then in building better leaders which includes a good section on self review and finally closing it by summarizing and restating the actionable framework.
Though every chapter had various gems of advice my favourite was chapter 4 on intention and attention.
This is a book which I would heartily recommend to both the emerging leader as well as the established ones. The former gains an actionable framework while the latter can validate their workings  against the framework and gain dine deeper insights.
