A security specialist gave me a good bit of password advise that I've used for a few years now.
Choose a song you know, take the first line (or two if they're short lines). Take the first letter of each word, and that's your password. Replace i or o with 1 or 0 and keep the correct capitalisation.
Take Stairway to Heaven as an example, that would give this password: Talwsatg1g
