In the infinite deck of cards that might be called human wisdom, which, of all the cards, might be called the joker -- the one card that fits with and improves any other card?
If I had to guess, my guess would be this: Get over yourself.
This is easier said than done, of course, and yet examples are all around us all the time. Birds, trees, sunsets, Chevrolets, shoe laces, coffee pots, book shelves, housing projects, dogs, cats ... and on and on. None exudes self. Each simply is self.
Get over yourself.
Just be yourself.
