When I first picked up this book I made an error of judgement. Noticing that it seemed quite slim, I thought I could finish reading it in just one or two sessions. However, what I had not counted on was the book’s living up to its title. In short, it made me think. It made me think about what the author was saying in its own right, that is whether or not I agreed with it. It also caused me to reflect on my own practice as a teacher and, now, as a consultant.
