Riccardo Corradin, a web development consultant and passionate advocate of test-driven-development (TDD), wakes up at 6:10 every morning and begins his day by drinking two glasses of water and doing twenty push-ups. For breakfast, he eats a bowl of fruit, yogurt, and Cruseli. He also adds plenty of sugar, explaining, "I don't feel like eating my breakfast with a sour face." After showering and getting dressed, he takes care of his papa tasks—getting his children, ages one and three, up and ready for daycare. Then he packs his lunch (a sandwich made with fresh, home-baked bread), before heading off to his client's office in Amsterdam. "It's important to enjoy your lunch, so I do my best to make something great out of it every day," he says.
