There are a few you need to remember, for example if you have a password manager then it would be worth memorizing one of those over the course of a few days. All the rest: use a password manager. I'd expect that not even the most brilliant 1% of this planet to have unique, 14-character random password for each account they own.

For special accounts, such as bank accounts, you could have a second password manager database with a unique password, if you are concerned that a password db which gets unlocked (almost) daily is not secure enough. Or remember unique password for those special accounts.
