If you want to take more control over your career I suggest you read this book. I found the exercises very useful in thinking about how I want to develop my career within the organisation I work for. I have found that further up in an organisation you go the more you need to develop influencing and networking skills and to do this it helps to have a clear idea of what you are aiming for. I have read a few career books in the past many are overly long or very much geared to the American market, whereas this book is international in it's outlook.
