Tim Ferries has been my idol for a long time. I read two and a half books of his. What fascinates me the most about him is how he hacks apparently common methods of approaching certain tasks in a completely different way than the average person would. He is confident that everybody can learn to speak a new language fluently within weeks or learn how to dance on a world class level in a couple of months, whereas others think they need a lifetime. The way he does it is not to learn every single nuance but rather only the essentials of each task to a very high degree. He does this by talking to experts in every field he is interested in, figuring out what is truly important about their field of expertise and what is just background noise. In his second book “The 4-Hour Body” he tries to hack sleep. For many nowadays, sleep seems to be an obstacle to get through. Many are reducing sleep to a minimum every night – or day, just the amount needed to get the brain going again. Tim experiments with different sleep patterns and different amounts of hours slept. Most people have a monophasic or biphasic sleep pattern, meaning that they get their daily sleep all at once or in two phases of sleep – like the Spanish with their siesta. Tim’s verdict is that no matter what sleeping pattern you follow, it is important to get enough REM sleep (2 hours) a night, which is when all the sorting of your brain structure happens. I’m a little skeptical if that is all a functioning body needs in the long run.
