Beware of other important considerations when writing down passwords. For example, law enforcement can demand that you hand over a sheet of paper, but they cannot force you to divulge a password from memory. But each password carries its own weight, so while you may care about this for your disk encryption, you may not for your social media account. There's also the risk of creating weak passwords so that they're easier to type. Ideally, your password would be generated randomly by a computer, or using other methods, like dice (e.g. https://www.eff.org/dice https://www.eff.org/dice).
