I recommend learning to use a password manager to automate creation of secure passwords and controlled by a single passphrase. 1. A good password manager can run or be made to run on many platforms, including mobiles and flash devices. 2. If you happen to use a single password frequently, then you should not forget it anyway regardless of whether you or a computer made it. 3. With throw-away/automated passwords for every site/usage, you can be more confident in allowing passwords to be saved for convenience in application password databases, e.g. browsers. 4. A good password manager should allow generating passwords based on common patterns which can be customized per site. Therefore, you become almost completely indifferent to the bizarre rules that some sites may require (since you only have to flick a few checkboxes once). 5. Password managers can easily measure and show you the entropy for your password. A good one to use is Keepass though there are other competitive ones.
