Writing in your head

On my old web site, I used to have a collection of a dozen or so sayings about the craft of writing. One of them ran to the effect of "If you sit down to write, but don't put anything on the paper, your intention was not to write." I've googled and can't find it, and I'm on my laptop without access to archives, so I can't dig up the original. So it goes.

But the point of it is this: You should never confuse thinking, pondering or musing with writing. And there is value, for me, in thinking without writing. If the definition of an extrovert is a person for whom no thought goes unverbalized, I don't necessarily feel the compulsion as a writer for my every word to exit my fingers into a keyboard or pen.

Sometimes, thinking, and being alone in my thoughts, is exactly what I intended to do.
