The age-old "don't write your password down!" mantra is not meaningful without clarification.
That is essentially, of course, how password managers work!
There's no reason not to write a password down as long as it's securely stored. You probably need embarrassingly little physical security to store your password more safely than many dodgy website solutions!
I _still_ frequently get my _already set_ password emailed to me in plaintext either on sign-up, or when I click "forgotten". (The site is always treated to an angry email encouraging a thorough redesign - though not of course, a 'reply', which would give them even easier access to my password!)
