Dedication

Any success I get is thanks to my family. I would not be who I am without their guidance. Special thanks to my mom, the best person in the world, who is everything in my heart. To my dear J, my friends, and my little dog, you all fill my life with happiness.

I dedicate this book to my beloved family. For giving me all the unconditional support and for their constant sacrifice in helping me become the man I am today. I love them with all my heart.

I dedicate it especially to my past self, to that child who fought very hard to achieve his goals. Little Erikson, we did it!
