after all the discussion of "writing rules" and the Holy Ten Laws of Writing as propounded (differently) by every author you ask -
here's the true holy grail of it all. What would you do if you could only do ONE thing?

I would also, however, like to offer
this piece Feel free to discuss. Play nice.
