Trick Yourself Into Writing Well by Telling Yourself to Write Badly
One of the best things about
Worse than thinking about whether what you're writing is good is actually trying to answer the question while you're writing. Aside from the fact that it means stopping to go back and read, evaluating your work is poison to producing it. Evaluation and generation are totally different modes of thinking, and soon enough you end up worrying about whether your writing is good before you've done the writing. And that, folks, is game over. Stopped in your tracks, paralyzed by worry, sure your ideas are garbage, there you are: not writing.
Okay, but so then there are you are, sure your ideas are garbage and not writing. What do you do?
Write the bad draft.
Make that your goal. Do it. You'll find it's a million times easier to get started if you tell yourself, "I'm just gonna write the shitty version of this" than if there's any pressure to make what you're writing good. Half the time, the "shitty draft" will be pretty good, anyway-once you turn off your inner critic, all of your writing energy goes toward writing rather than worrying about your output-but even truly shitty drafts can be revised to greatness. There is so much you can do in revision, from overhauling structure to drafting new paragraphs to tweaking the language of a sentence.
You just need to write a first draft first. So write a bad one.
