" The book offers "small things" as the ways to improve businesses or management. The way this book is written, ie. the informal languages could undermine your understanding or even frustrate you when you see some lines repeating themselves (purposefully). The informality didn't mean you can relish this book without some knowledge in management, e.g. knowing who's B.F. Skinner. The practical advice offered by the author is actually common sense, like the power of saying thank you and appreciating others' efforts. There are no mind-boggling scientific discoveries/theories, if you are enticing these in this book, it's going to let you down. Instead, what you could get are trivial matters, often get unnoticed by higher-ups, ironically. It can't offer me much knowledge, probably because I am not managing a business for now, and it really took me a lot of time to finish it. Hence, I gave it 1 star. "
