A quick tip that I sometimes forget. Complicated ideas are often really hard to write concisely. When I try to compress an idea, I find that I start to lose accuracy, or add ambiguity. The thing that works best for me is to write it exactly how I’d explain it to someone, without worrying about it being too long, too wordy, redundant, or anything else. I just get it out on paper. Then I have something to edit. Once it’s on paper, I can start to kill off the stuff I don’t need and reword the stuff that’s awkward. This works for me whether it’s one sentence, or a whole paragraph. Does it work for you?
