There are plenty of books about body language on the market but this is more clearly illustrated than most, which is obviously an important advantage when the power of first impressions is the principal theme. This one also describes in detail what you disclose about yourself before you open your mouth, just from the way you stand, sit and maintain your posture. But, again, where this book is different is in the clarity of presentation and the systematic treatment of what, in all that detail, can all too easily be a confusing and quite perplexing subject. In other words it promotes an understanding of body language without also promoting self-consciousness, and demonstrates through the language of book production how little of what we communicate is conveyed by what we have to say.
