A PERSONAL NOTE FROM HARLEY HAHN
This book will change your life. That’s a strange thing to say about a computer book but, as sure as you are reading this introduction, your life will be different by the time you ufb01nish the book. You will think differently and you will approach problems differently. You see, your computer is not a lifeless piece of machinery. It is a dynamic tool that interacts with your very thought processes. Whenever you use a computer it becomes, for better or for worse, an extension of your mind. This means that, over an extended period of time, the computer system you use changes how you think.
