Any significantly genuine attempt to remember the password will reduce the entropy to such an extent that your rpi could crack it. The fact that in our brain the fragments are hopelessly jumbled and you forgot if you added 1999! or 1990? to the end does not mean a computer cannot achieve a significant shortcut.
