I personally like the method of loci for remembering things. Its been used since ancient Greece.
I like it though because of the name. Loci rolls off the teeth easily.
If I use a mind palace though I would use a crazy, spooky, Gothic castle, and every door would have a monster that scares the crud out of me. That way I would really remember the things behind the doors.....or i'd poop myself. Ether way something would get done
