I am very happy and proud that I was able to write this book. While writing the book I improved some of my personal skills. For example, I improved my english writing skills (at least I hope so :)). I learned that it is very important to be focused on a certain topic instead of jumping through chapters. I improved my organizational skills, I learned to be patient, critical to myself and to be tenacious.
