As a writer, what causes you to come to the realization that another revision to your finished (or so you thought) manuscript is inevitable?
Is it during a cosmic, enlightening moment that you discover the need to venture on yet another cycle of revisions?
Probably not! Most usually it is as simple as:
You’re crossing the road, minding your business. Suddenly, the wind shifts slightly (that only you can perceive), and boom, you feel a revision coming on – a revision that will suck you inside a deep hole and deposit you in a world full of variables and new experiences. You will end up feeling somewhat akin to how Alice must have felt when she found herself, not entirely by her own volition, in Wonderland.
Okay, so I exaggerate … but you get my point?
