I have a different experience personally quite a few of my side projects end up being put on the back burner after a few days of code when I realize I should’ve over engineered and I’m going to have to spend some time refactoring/reengineering if I want to continue though I also have a lot of scope creep where I’ll start with one idea in mind get there or near there and then want to start adding stuff or changing the end product

True, but in a longer term? where the curve filters out the side projects which arent viable and others will make it to a inevitable point of scaling?
