That book was basically a collection of productivity hacks for people with a product to sell, giving them the opportunity to cut down drastically on the amount of work they had to do while keeping their revenue streams up.
The message for me from The 4-Hour Workweek that sticks, though, is not the main message of the book, which is essentially how to get rich while other people handle the tough work for you. It’s that it’s an instruction manual for stuff that Ferriss tried himself, using his own business to experiment on.
And so we pick up Ferriss’ second book,
That brings us to the punchline, about how this book really does change your life.
The takeaway: It’s OK to experiment on yourself.
Sure, it’s nice to have a physician available, especially if you don’t understand the chemistry at play in your body and in certain drugs. And if you are trying new stuff for the first time, having an urgent care or emergency medical facility nearby is a good thing (and maybe you want to have a ride available, just in case). But to be honest, while the body can be a fragile thing, it’s also really resilient, and it lets you know when you’re taking it too far through pain or other reactions (like swelling, for example).
But in general, you should really learn to be comfortable trying new things, and also observing how they affect you. This applies to food, activities, sleep and pretty much any part of life you want to apply it to.
To observe correctly, however, you must measure and document. Ferriss has done pretty much all the work for you. If you want to lose 2% body fat in two weeks, he’ll give you the shortcuts. If you want to put on 18 pounds tomorrow, he’ll let you know. But he also lets you know how to measure and document your progress, so you can see for yourself, and that’s the part of The 4-Hour Body that’s most interesting to me.
Why it’s important: It makes you the expert.
You don’t need a personal trainer, or a dietitian or a scientist. You record what you eat, you record how you feel, how it changes your weight, etc., and you do it again under the same conditions at another time to see if there were any extraneous factors (that is, to see if it’s replicable).
You would be the best expert on you, if you were to pay attention. And, the punchline here, is that you can extrapolate all you learn to other parts of life. The observation, data collection and other skills certainly translate outside of eating and running.
How to use it: Ferriss himself leaves instructions for how to use the book. Pick a couple of chapters that are relevant to you, and read those first. Utilize the tips. Do your experimenting. Then read the rest of the book if it’s interesting to you.
