For me that is a resounding yes, Not the what I did so much as the why and how. Particularly for thigns that I only do with a fair amount of time between iterations. If I don't take good notes on what I did last time, the results and why I changed to the current steps I find myself redoing old ways that didn’t work. At least with a good note set I can start and move forward on reach iteration.
Which is why I emphasized the question was non-rhetorical. There are lots and lots of really good reasons to do it. It's been my experience in ten years of participating in this forum, though, that some of us -- and I myself am chief among them -- do things for a sense of security that we don't actually get value from. Those activities become burdens rather than enablers.
@bcmyers2112 There are many things that are not documented properly and you've got to search the whole internet to find the details of the procedure. Even ChatGPT doesn't know the answer. So it is worth recording somewhere when you discover how things work!
