Time for a variation of this ol’ chestnut again, because it’s perfect anytime:
Today, write the worst possible thing you can manage to write. Better yet, think about the work you must aspire to do and try to tackle some of it by writing part of it as badly as you possibly can.
Sounds ridiculous, to be sure, but it’s also a magnificent trick to get the hell out of your own way. When we set off to write under the auspices of writing badly, that snotty part of our brains that tells us we’re not good enough and that gets us caught up in perfectionism to the point that the blank page gets intimidating? Nowhere to be found. G’head. Try it for yourself.
