Obvious..............................................

"The obvious is that which is never seen until someone expresses it simply."
-Kahlil Gibran

This quote reminds me of the story of Christopher Columbus and the Egg.   Full story here.  Excerpt here:

An egg of Columbus or Columbus's egg refers to a brilliant idea or discovery that seems simple or easy after the fact. The expression refers to the apocryphal story of how Christopher Columbus, having been told that discovering the Americas was no great accomplishment, challenged his critics to make an egg stand on its tip. After his challengers gave up, Columbus did it himself by tapping the egg on the table so as to flatten its tip.
