We had a similar part-thread last October -- to save overloading the search function, I modestly repeat my post:
One of the New Statesman competitions [in 1969] was to invent aphorisms or proverbs of a self-evident nature, the example being an Ashanti proverb "Do not rub bottoms with a porcupine".
Correspondents came up with the following [a selection only]:
He digs deepest who deepest digs.
He who has the biggest feet will cover the most ground.
A bird in a taxi's worth two in a bus.
If there's no lead in your pencil you don't need a rubber.
