Everything in Nature contains all the powers of Nature. Everything is made of one hidden stuff.

The same principles turn up at every scale, in things that appear to have nothing in common. How a conversation goes wrong and how an organisation goes wrong follow a recognisable shape. Learning something deeply in one domain very often hands you a tool that works in another, because the underlying structure repeats.

When you understand something well, ask where else that pattern shows up. A rule about how water finds a level may explain something about money or attention. Look for the shape rather than the subject, and your existing knowledge starts working in places you never studied.
