Happy for you that you receieved a good outcome of this. I can relate to your post. I think many, even OGs, have our mindset from the legacy system, that on purpose learn us to me naive and dependent on them. I have started engraving my password or keys on metal plates. Dunno if it is more secure than paper, but I feel very responsible doing it.
