> write passwords down in places that are easy to find (like post-it notes next to the screen)
Writing passwords on post-it notes is often used as a ridicule of non-tech-savvy folks behavior. I'd like to pose this question: If you're doing this not at an office, but at home, is this really so bad?
Say you run a web site on AWS and write your really long AWS password on a piece of paper at home. It would take a hacker finding out where you live and breaking into your house to find the piece of paper to access it. On the other hand, your ordinary neighborhood burglars typically care about cash and jewelry in your house, not post-it notes with passwords. It seems those two categories of intruders rarely overlap, unless you're a world famous target.
