A common misconception is that the experience of making art should feel like experiencing a finished work of art - refinement, release, beauty, revelation. Actually, it is challenging to do creative work and bring something into the world that wasn't here before.
It was comforting to hear Malcolm Gladwell's consideration of artistic refinement in his podcast last year (Listen here: http://revisionisthistory.com/episodes/07-hallelujah). He talks about Cezanne working on the same subject repeatedly for greater refinement, often with a lot of dissatisfaction propelling the process. Gladwell also explores how a piece - the song Hallelujah - was brought into its fullness by a number of artists working together over decades. Art takes time!
One of the primary dead-ends to being creative is waiting until I feel like making art. I find that I have to dive into the work itself and make the act of working the reason to be there. This relates to the practice of yoga described in the Bhagavad Gita:
"To action alone hast thou a right and never at all to its fruits; let not the fruits of action be thy motive; neither let there be in thee any attachment to inaction."
The real "work" of art, and the work of growing, involves going into the unknown. For me, it feels more like bushwhacking through the wilderness of my resistance and fear, and less like receiving sprinkles of easy inspiration and pixie dust ;)
What does the process feel like for you?
