I remember reading an article about complex passwords vs what was basically called "offensive gibberish", I've actually taken a liking to this approach more recently than relying on a password manager. The whole goal is to make your password memorable while also making it long and complex enough to avoid cracking/brute forcing.

e.g. For gmail rather than "password3" one might use "give me my god damn email you stupid machine!" It's great because it's easy to remember, and complex enough to keep you relatively safe.
