Leverage isn’t just useful in physics. Rather, it’s a principle that applies across our lives.

Leverage lurks in the background of nonlinear outcomes. Consider the author who took the ideas in their head, put them in a book, and sold millions of copies, or the Wall Street investor who made a single decision that resulted in billions. Or even the CEO who directs the people working for them. All of these examples are leverage in action.

When you truly understand something, you can express it at any level of detail while maintaining coherence.

The master can provide the one-sentence version, the paragraph version, and the chapter version, all of which tell the same story at different resolutions. The novice can only repeat what they’ve memorized at one resolution.
