Kasper van der Meulen is a best-selling author, science teacher and lifestyle adventurer. He went from being overweight, burnt out and unhappy, to developing superhuman focus, fitness, and personal freedom. Kasper put himself through numerous experiments and challenges. He optimized his lifestyle, conquered the cold, ran ultra marathons on his bare feet, tested countless diets, read a ton of scientific literature and explored as many esoteric practices he could find. With over ten thousand hours of experience in teaching science, self-mastery and innovation, he decided to demystify and methodize these principles in a fun and bite-sized manner. As a final test of his focus, he wrote his book within 30 days, so that he would have to practice everything he preaches. This is a fantastic episode!
