What random ideas from courses have been valuable?
In another thread, @Susan Moore writes: === I've taken courses that I didn't finish. But the amount of studying I did do, combined with related unfinished courses, and my own work and life experiences has all added up to this cumulative knowledge and insight I simply would not have without my messy inclinations and unfinished courses. === In that thread, I had an example of a course I didn't finish or implement when I got it, but which still gave me an idea that ended up being useful to me years later. This got me wondering, have you had experiences like that? I mean, have you ever found... A valuable idea or tactic or strategy that you got from a course that you never never finished? Or an idea or tactic or strategy that you got from a course, which you didn't use at the time, but which you used and profited from years later? Or a a tangential idea that somebody dropped in a course or training, which you ended up using, even though it was almost irrelevant to the main thing being taught?
