I absolutely could not have written this book without the love, support, and encouragement of my wife Melanie, who got me unstuck when I needed it and who reminded me that the chapters were good enough, or else I'd still be writing Chapter 1. I want to acknowledge my two beautiful boys, who in the past year never saw dad without the laptop—you both are the reason I've accomplished anything at all. I'd also like to thank the fine folks at Packt Publishing, including Subho Gupta, Pranjali Mistry, and of course, Arshiya Ayaz Umer, whose patience never ran out, even when it should have. Thank you for giving me the opportunity to write for you once again and for believing and trusting in me throughout. I'd like to thank my friend Jennifer Fabrizi, who was kind enough to read some of my work when it was still in the larval stage. Thanks to Rob Edge for giving me a much-needed break from thinking about UX one night a week. Thanks to James Wachira because how could I not thank you? Thanks to Greg Renoff, the author of Van Halen Rising, who was kind enough to thank me in his book, so I am returning the favor. Thank to Starbucks, Whole Foods, and Panera Bread for allowing me to sit for hours, even during lunch time, as I wrote and rewrote these chapters while consuming most of their coffee. Lastly, I'd like to thank you for buying this book and for taking the time to read what has been the top priority of my life for the past year.

I am grateful. Thank you.
