John Muir once said, “When we try to pick out anything by itself we find it hitched to everything else in the universe.” Fields are studied individually, but there are so many common denominators across topics. The more fields a lesson applies to, and the more disparate those fields are, the more powerful and important the lesson becomes. @morganhousel
Leibniz’s Worlds (philosophy): There are infinite possible worlds; we just happen to live in this one. Some ideas hold true in all possible worlds, while others would only work in this specific iteration. Naval put it this way: “In 1,000 parallel universes, you want to be wealthy in 999 of them. You don’t want to be wealthy in the fifty of them where you got lucky, so we want to factor luck out of it … I want to live in a way that if my life played out 1,000 times, Naval is successful 999 times.”
Liebig’s law of the minimum (agriculture): A plant’s growth is limited by the single scarcest nutrient, not total nutrients – if you have everything except nitrogen, a plant goes nowhere. Liebig wrote, “The availability of the most abundant nutrient in the soil is only as good as the availability of the least abundant nutrient in the soil.” Most complex systems are the same, which makes them more fragile than we assume. One bad bank, one stuck container ship, or one broken supply line can ruin an entire system’s trajectory.
