Have you ever tried to read a book but found that every time you reach the end of a page you can't recall a word of it? This usually happens because (a) you're not concentrating properly, (b) the book is not written well, or (c) the language is unfamiliar or written in such a way that you can't relate to what it is saying.
There are a lot of positive reviews of John Lees' book. Let me begin by saying that I agree wholeheartedly with the sentiments of most of them. The book is indeed packed with great information useful to almost anyone trying to work their way through a career dilemma. However, I found that the prose often falls into category (b) and occasionally (c). For some people stylistic woes such as this aren't a problem but if you're anything like me you may want to take note before purchasing.
I like to get my money's worth after purchasing a book. I read from cover to cover initially before returning to dip in and out. If you're the same you may be in for a frustrating time. Sure enough a lot of chapters are fine, especially some of the later ones which address certain issues directly and can be read independently. However, other chapters, especially some of the earlier ones which deal with more general matters, can be terribly frustrating. While the style is accessible, often the choice of words, the sentence structures, the way one sentence or paragraph doesn't quite flow into the next, the way an analogy doesn't quite fit and the way an exercise is recommended but not properly explained can be headache-inducing. I found I couldn't simply read each chapter through and then come back later as is my habit. Instead, I had to keep stopping all the time just to try and square in my mind what he was driving at, how his anology applied or how what he was saying related to me at all.
In summary: the book is packed with useful information, but because of problems with the prose I feel I can only give it three stars. I found it very difficult to follow in places and I found myself constantly having to stop to re-read paragraphs and pages over and over. I think Mr Lees would do well to consider rewriting some chapters for the next edition.
