Password hints and reminders can help to jog your memory and help to avoid creating another password.
If you can create your own password hint make sure it only makes sense to you. It should never contain your password.
If you use a service with preset questions E.g. What was the name of your first pet? try to make your answers humours and abstract, e.g. use an inside joke, or your little brothers name! This will insure it is both memorable and not easily guessed.
