I would like to dedicate this book to Annette and Tommy, for being so supportive and encouraging whenever I work on projects that sometimes eat into our quality time together. This book is also for the reader–having taught thousands of IT Professionals over my career, I hope this book reaches a greater audience and helps you achieve your career aspirations. Work hard and aim for the stars!.

Writing this book has been a team effort, and I am delighted to have been a part of that team. Aside from the folks at Pearson and my co-author, Andrew, I’d like to mention my dog, Lucy. Her enthusiasm for long walks undoubtedly helped me clear my head, and thus to deliver chapters on time to our editor, Trina Macdonald.
