I've thought for a long time that a huge amount of business advice is cargo cultism, since the actual underlying determinants of success are so complex and hard to pick apart. Anything far beyond the basics of value, product market fit, making something that costs less than you can sell it for, etc. is a bit suspect, especially if it starts to wax hyperbolic about ephemeral character traits and other wooey things.
