I've always liked this one:
First get it written, then get it right.
(not sure who wrote it)
Writing is like driving at night in the fog. You can only see as far as your headlights, but you can make the whole trip that way.
And since I'm in the type of mood that can use a motivational pick-me-up, I searched around for more...the following are the ones I like.
If you can tell stories, create characters, devise incidents, and have sincerity and passion, it doesn’t matter a damn how you write.
I need to tattoo this one to the back of my hand right now:
It is perfectly okay to write garbage—as long as you edit brilliantly.
Haha, I like this one because it goes along with what I always say about published writers...there are some really crappy books out there still getting really famous. So I need to just keep my chin up and remain persistent...if this is what I want to do, there's nothing stopping me but me:
It took me fifteen years to discover I had no talent for writing, but I couldn’t give it up because by that time I was too famous.
I think I'll end with this one, since it feels like my life right now:
Half my life is an act of revision.
And my all time favorite quote, which has nothing to do with writing:
If there were a mile-high mountain made of granite and once every 10,000 years a bird flew past and brushed it with a feather, by the time the mountain eroded away, only a fraction of a second would have past in the context of eternity.
-Lois Duncan (which I just now learned by googling the quote)
