Written by a normal guy, who turned his struggles into superpowers 🚀

Hi! My name is Kasper van der Meulen 🙂
I am an author and lifestyle adventurer. I went from being overweight, burnt out and unhappy, to developing superhuman focus, fitness and personal freedom. I put myself through numerous experiments and challenges. I optimized my lifestyle, conquered the cold, ran ultramarathons on my bare feet, tested countless diets, read a ton of scientific literature and explored as many esoteric practices I could find. With over ten thousand hours of experience in teaching science, self-mastery and innovation, I decided to demystify and methodize these principles in a fun and bitesized manner. As a final test of my focus, I wrote this book within a month, so that I would have to practice every single thing I preach. Thanks to the principles in this book, I’ve managed to live a life of empowerment and freedom, and I sincerely wish you the same! 😃🙌🏻

But this book isn’t about me, it’s about you!

It’s about helping you find your own way to finally get the results you’ve always wanted. If you take only 10 percent of the information and ideas in this book and put them into practice, it will change your life.

I promise!
