Found this interesting piece by Marshall Vandruff where he outlines some ideas about creativity. I especially like the third point, about finding your own ‘voice’.
1-Find how things are similar using metaphor. For example:
A little boy is a monkey.
Apartments are filing cabinets for people.
Fireworks are dandelions.
2-Find things that are different using opposites. For example:
The smoothness of a woman’s skin placed next to the scaliness of an alligator.
The chaos of a crowd placed next to the order of columns on a Greek building.
The bright colors of a rainbow hoovering over a dark and shadowed valley.
3-The more creativity feels like recess, the more likely you will do it well. For
example, if you want to create detailed paintings that are as real as your own flesh, but you cannot sit still for a minute, it will seem like torture for you to create this kind of slow and carefully rendered art. If you find a way to create to fit your jumpy, quick nature, you will love, do it all the time, and eventually become great at it.
