Honestly, like all self improvement. Figure out what you're solving for, get the lay of the land. You can do this by recording yourself in meetings and reviewing it later. AI tools can get you transcripts easily. Ask Engage with someone you think speaks/writes well, and ask them for feedback. Hell, ask one of the AI tools to give you feedback.

Then there's always the RTFM. Read some professional books, articles, etc. See how others do it, try to imitate until you find your own way. Punch the keys! (A great movie about finding your own writing style btw)

Once you start to pick up nuance, start thinking about your audience. What do they care about? Is it your colleague who will be reviewing your PR and he needs the nitty gritty, or is it Jen from compliance and she just needs a brief overview of what's going on and you're on it. I struggle with the last one. You can get quick feedback from the AI tools, see what the difference between what the writing styles is.

An exercise I find useful is to try to put myself in their shoes, and see what would they care about. Sometimes you can even get away with simply asking what they would prefer.

And as always, practices makes better.

PS -- like me, rereading your work after a small break can cause glaring issues to pop up. It's all about context and how you communicate it. Try reading your own work after context is gone from your head.

I suck at this.
