I've found memory palaces need at least some upkeep. I only ever used it once to memorize some silly list of matrix properties for extra credit on a test and it worked really well, going along a chain of symbolic objects placed along a location I know very well (the first homeworld of Spyro 3), but it faded over time and now I only remember one thing from it.
