“The greater the artist, the greater the doubt. Perfect confidence is granted to the less talented as a consolation prize."
Robert Hughes

See, it is good to have a head full of what was I thinkin' when you read your lyrics the day after creation.

“What we do see depends mainly on what we look for. In the same field the farmer will notice the crop, the geologists the fossils, botanists the flowers, artists the coloring, sportsmen the cover for the game. Though we may all look at the same things, it does not all follow that we should see them.”
John Lubbock  

Yep. How about songs? What we hear depends on what we listen for; a bass player will hear the bottom, lyricist the words, guitar player the chops, singer the singing, publisher the flaws, NSAI critiquer the structure, songwriter the metaphors, radio listener the melody and on. Tune in so all parts are heard as a whole. Imagine looking at an colossal red oak tree standing alone in a field. Thousands of pieces joined together making one tree.
Like a finished 5000 piece jig saw puzzle see both at the same time.
