I would like to thank the people who have encouraged and assisted me with this book. I have always been an optimist; I believe it to be my greatest asset. However, without the support and enthusiasm of friends and family a dream such as writing a book can easily go unrealised. First, my sister, Wendy Bateson. Success is measured in many ways but I have no doubt that Wendy was the most successful person I have ever known. Most of my drive and all of my ambition are thanks to her.
