Better advice is to use something such as PGP/GnuPG/etc to encrypt all of your passwords with a single, next-to-impossible-to-break passphrase (ie. use a complete mocked up sentence). Yes, you forget that passphrase and you are screwed, blued and tatooed (just where did that phrase ever come from, anyway? and more importantly, why did it suddenly come out of my mouth... hehe).

But yes... I keep all of my passwords encrypted and signed to me, with my own public key, "for your eyes only," in one of the many encypted files on one of my machines... you can also use something like Secret! for your Palm, if you're in to the PDA thing...
