This used to be my main approach, but now I only use it for some key sites and rely on a password manager for the other 90%. Why the change? Watching the mental deterioration of aging on friends and family, and noting the beginnings of such things in myself. My mind is so much slower than it used to be, including recall. It's not only aging. A friend had a concussion from a lousy picture frame falling off the wall. It wasn't even that big or heavy. 3 years later still slowly rebuilding mental and language function.
