“The fox knows many things, but the hedgehog knows one big thing”.

The Fox and the Hedgehog

If you want to remain aloof and mysterious, keep this phrase in your back pocket and never bother to explain it’s meaning.  Use it at dinner parties, coordination meetings at work, all-staff presentations, arguments that you are painfully losing (this is more often than the case with my wife) or; when you’re disciplining your pets, you’ll be a hit no matter where you use it.
