Leverage is usually the means of exchanging direct force for
control. Let's consider the clockwork of a mechanical watch as
an example. The gear work of the watch (the leverage system)
refines the force gained by the winding up mechanism, and
punctuously parcels it out to be able to move the hands of the
clock. How to leverage? Observe the system. Understand the
system. Find the strengths and the weaknesses. Find the key
points. Understand the dependencies. When you understand the
system, apply the minimum necessary force at the key points to
make the system work the way you want it to. If there is no
system, build one! If you have a big goal, break it down to
small steps, and if you can, use a leverage system to move
forward ten steps for you when you make one. Using brainpower to
leverage force is the advantage humans have. If you learn the
general idea of how to leverage, you can apply it to all kinds
of aspect of life.
