I always looked up to good and famous designers/authors as if they had the answers to all design problems. However, eventually I found out that design is not about the answers, it's about asking the right questions, and even these great designers are, in the end, only humans. There's no correct way or formula on how to do things or solve problems, it's about choosing a path and trusting you're doing what is best for each problem you're faced with.

This book would not have been possible without the support of my lovely girlfriend Márcia Gaudêncio. Thank you for all your help and patience, and for all the meals you cooked and chores you've done that should've been my responsibility, while I was busy with my laptop for hours on end.

I'd also like to thank Rebecca Youé for offering me the chance of writing my first book, as well as the Packt Publishing team and reviewers for their great work in reviewing and helping out over and over again.

Last but (definitely) not least, I'd like to thank my father, António Redondo Pratas, and my mother, Leopoldina Correia for giving me all they could ever give me, making me everything that I am today, and teaching me all that I know and do. You can't find these things in any book. Obrigado!
