I am glad to say that I have not regretted this purchase. :)
You realise that this book is a no-nonsense, straight to the point tip book, the moment you flip to the content page. The elaborations are concise and punchy. You don't have to mull through numerous pages of boring academia but you get very useful tips. Sharon Bowman is quite obviously an old hand at training.
What I also loved were the punchy and witty little words of wisdom that Sharon Bowman boxed up in various parts of the book. It made lots of common sense when you read them, and of course, served to tickle your funny bones.
My only reservation about this book is that while the tips are great, its suggested games/pair shares do not seem very useful for most situations - to some extent, these pair shares can seem rather common and boring.
Nevertheless, I would take this with a pinch of salt, and rather use these suggested games/pair shares not as the hard and fast model answers, nor as templates, but more as suggested examples. Ultimately any game can become boring and mundane if too many people keep repeating it in different trainings. Your job as a trainer is to make sure this doesn't happen, and that creativitiy is always maintained.
