Seeing that this is the second book I have now written; the process is becoming much easier. I still make mistakes, correct them, and then make some more. However, I welcome the feedback that I get from my family, friends, and colleagues who have helped review it all along the way. I am very surprised how fast Drupal 8 has moved and improved along the way, all for the better. During this journey, I must reflect on the one person who instilled in me my work ethic, my father; he was a tough man, but I respected him. He has since passed away and while I know he shines down on me, I can still hear him telling me to push myself, love my family, and respect everyone. While I did not get a chance to say goodbye to him, I know he knows how much I love him. Speaking of family, I have been blessed with two great moms, an awesome brother Josh, and a beautiful sister Carly. However, the most important person to thank is my wife, Rebecca. She s been my biggest fan and without her, none of this would be possible. She kept me sane on long weekends and late nights of writing. She made me laugh when I wanted to scream or cry. She took me on long walks, longer hikes in the Appalachian Trail, and even to one of the Seven Wonders of the World, Machu Picchu. However, after 25 years of marriage, I still think you re the greatest wonder in the world. Finally, a huge thank you to my colleagues at Forum One: rock star developers, awe-inspiring designers, breathtaking UX, and amazing marketing. Hey Drupal! Come for the code, stay for the community.
