“Everybody has a secret world inside of them. All of the people of the world, I mean everybody. No matter how dull and boring they are on the outside, inside
them they've all got unimaginable, magnificent, wonderful, stupid, amazing worlds. Not just one world. Hundreds of them. Thousands maybe.” -Neil Gaiman
You could go with a motif, maybe the wind, and then change the representation when your mood changes.
Good idea. Usually I have a motif going... romanticism... books/knowledge, nature, music, imagination... but your suggestion might be helpful when I get stuck in one of these "What do I choose?!" modes.
“Thoughts are the shadows of our feelings -- always darker, emptier and simpler.”
