Alex Linley's book "Average to A+ - Realising Strengths in Yourself and Others" was a lightbulb moment for me - not just for being more productive in the workplace (the basic concept is that if you play to your strengths, you work more efficiently and are happier too), but also for getting more out of life. This new book takes that one step further, by unpackaging the range of strengths available to us, with plenty of case studies and practical advice along the way. So this is great for managers who are under pressure to make productivity gains: if you want your staff to work more efficiently, you can use this as a tool to organise them around their strengths. And if you're unhappy at work, this book will help you to move to a place where you are a round peg in a round hole. Highly recommended.
