When in doubt, simplify: Worried you’re not using the right words? Use simpler words. Worried that your sentence isn’t clear? Make a simpler sentence. Worried that people won’t see your point? Make your point simpler. Nearly every writing problem you have can be solved by making things simpler.
This should be obvious, but people don’t like hearing it because there’s the assumption that simple = stupid. But it’s not true; indeed, I find from personal experience that the stupidest writers are the ones whose writing is positively baroque in form. All that compensating, you know. Besides, I’m not telling you to boil everything down to “see spot run” simplicity. I am telling you to make it so people can get what you’re trying to say.
Ultimately, people write to be understood (excepting Gertrude Stein and Tristan Tzara, who were intentionally being difficult). Most people are, in fact, capable of understanding. Therefore, if you can’t make people understand what you write, most of the time it’s not just because the world is filled with morons, it’s also because you are not being clear. Downshift. People will be happy to know what you’re saying.
