Without taking away anything from your dad or what he said, the more
you know about impedance, or hammers, the pickier you'll be about
choosing a particular hammer for a particular job.  The hammer has to
match the size of the work and what you want to happen to it.

But as a very rough guide you use small hammers to change the shape
of things and large hammers to move them.

If you're used to thinking in terms of Fourier analysis, little
hammers do the high-frequency bits and big hammers the low.
