" Aside from the fact that the edition I read was an advance copy, thus there were more than a few grammatical errors, the sheer style of Coyle's writing was just substandard; or at least fell short of my personal standards for self help books. Having not read any of the author's previous works, nor having much preparation for this book, I wasn't overly skeptical at the onset. In actuality, many of his tips were insightful, though it consistantly references studies and people and fails to cite sources. Aditionally, Daniel Coyle too often uses the word "hotbed" yet never fully explains what this word means in various contexts. I won't advise readers to steer clear of this guide, and perhaps you may find it much more envigorating and applicable than I, yet I will surmise that I didn't love it and would be surprised if it were to be on a bestsellers list anytime soon.
