Lol. First, start cleaning up your own room! If you're old enough to be on Bitcointalk (for 6 years already), you shouldn't need your mom to clean up after you.
You took the word out of my mouth. I don't even know how OP thought that would sound to those reading this post.
Back to the question raised in the OP. For me I like to keep my secret phrases or password on a booklet containing other valuable articles and write-ups. Writing it on a booklet or two booklets as a way of duplicating them helps much. Copying passphrases/passwords online or storing them on the cloud or emails is a no-no for me. I like to keep it simple. Don't use a distinct booklet. Let it be on a booklet that won't trigger scrutiny of preying eyes.
