I've learnt that blogging is a necessary part of my practice for finding and exploring new ideas. It's brought me work and friends. And there's especially a place for blogging today: no platform will value your words like you will yourself.
I usually have ~10 drafts of different posts and many of them are basically "project logs" that I transform into a post over days/weeks/months.
I restored some of my content from there a few years ago: https://simonwillison.net/2017/Oct/8/missing-content/
idea capture is upstream of everything else. you can do drafting or editing a month later or a year later, when the mood comes
I wrote a Colophon recently about my blog tech stack. it includes a "Writing" section which touches on how I start with idea capture (and also the psychological blockers about doing everything else)
