The person who understands the mechanism gains leverage over the outcome.

Knowing that something happens gives you very little. Knowing how it happens gives you places to intervene, because every step in a mechanism is a point where the outcome can be changed. This is why understanding tends to beat effort in the long run, and why the person who takes the time to learn how a thing works ends up able to shift results others treat as fixed.

Pick something in your life you experience as simply happening to you, and spend an hour learning its mechanics. Money, sleep, how decisions get made where you work. Look for the step you could actually touch.
