You can't break 'em until you know why they are besides what they are.
I teach highschoolers, and quite frankly, they have a need to know how
to make what they want to do better, more effective, more expressive,
and more forceful (remember those years?), and with a few down and
dirty, quick and easy, elements and principles, you see their eyes light
up, with the old aha!, and they are off and running. THEY actually KNOW
when something isn't quite "right", but don't have the years on the
planet to know what to do to "fix" it, so they yearn for "rules".
I think the challenge is to stay within the rules, and just look like
you are breakin' them....anyway, that has been my teachin' motto...and
guess what? whenever they try to call me a rebel (and believe me, I am
one!), I can cite them verse and chapter on THEIR rules, and how I fit
between the parameters.
