If you have so many passwords, why not use a password manager?
Also there are some ways to create memorable and long passwords. E.g. I'm using short pictureable phrases and their translation in another language, sometimes adding a numeral if required. Example: "2YellowChopsticksZweiGelbeEssstäbchen" (even with spaces if allowed)
Very easy to remember for me, very high entropy, decent entropy if the pattern is known and requires a hand-crafted dictionary attack that even needs decent translation. E.g. in the example above chopsticks has two common German translations and the ä can also be written ae. Bonus points if you use it for a language you are currently learning.
The passwords are on different systems, you sit at a console. You have to change them regularly. I can use long DICEWARE style passwords for SSH, but I'd rather just have it use scrypt.
Though I have thought of having a mechanical typing device, actuators for each key, that would just type them for me. But it would be conspicuous.
I do use keepass for all the hundreds of other passwords where possible.
