When I wake up, I do my morning ritual, then I work for 1 hour on the most important task, and then I walk to the office - it takes about 30-40 minutes, and I listen to an audiobook during that - I arrive super-energized to the office. In the evening, I walk home, too. It's AWESOME. It's the simplest way to become a super-fit genius. And if I get stuck during the workday, I will take a short walk, too.
