First of all, I would like to thank my girl, Verónica, for her essential support while writing this book. Without you, this manuscript would have been simply impossible. But, most importantly, thank you for sharing your life with me. I would also like to thank to my sisters, Yoly and Inma, for all their help, not only with this book, but in life in general. Thank you for being always there. In addition, I want to dedicate this book to my nieces, Andrea, Silvia, and Laura, who are the most amazing people in the universe (at least the part I know). I also would like to remember here my parents, Pablo and Dolores. There is nothing I would like more than if you were here. I know that a part of you is living with us, in your daughters, grandchildren, and myself. I miss you so much. Finally, I also want to dedicate this book to the most important person in the world, my little boy, Pablo. Son, whenever you read this, I want you to know that I learned what happiness really means by looking into your eyes. I would like to believe these words can travel in time and space to give you a big hug anytime. Remember that your parents love you more than anything.
