For as long as man has lived the human race has been collecting tiny stipulations on living life. They're carved into the stone from the Temple of Apollo and etched in writing on the wall of Pompeii. They are featured in the Shakespeare plays, the commonplace book of Shakespeare as well as the book of commonplace from H. P. Lovecraft and the collection of proverbs by Erasmus, and the ceiling beams from Montaigne's study. Nowadays, they're recorded on iPhones and also on Evernote.
