Have you thought about using a master database program for such things? That way you only really have to remember one master password and then you just save username, pw, url, and sec question/answer in one repository. Something like KeePass... or any other the other ones out there. Could also just save an excel sheet which you pw protect.

Another method is to simply save them on your phone in contacts like:

Jimmy Smith (Army Buddy)

password@gmail.com

As long as you are only saving the password and not necessarily anything about that pw except an occult reference you understand, it isn't awful.
