I have a tendency to generate nonsense words which I can easily remember, and I'll then modify them to suit the password requirements (captials, l33tsp34k, etc.) Occasionally I'll glom a few words together with l33tsp34k filler (hypothetical example: 2BORNOT2B). Work passwords have strict rotation rules. My main non-work password most recently changed when I accidentally published it on my website through a combination of poor software, lack of proofreading, and muscle memory. Work and non-work passwords are (obviously) different, which causes me no end of grief when e.g. logging into my home webmail client.
