THE IMAGINATION
Sometimes a concept is so startlingly true it takes my breath away.
Here is a quote from A.O. Scott in this morning's NYT: "...the imagination lives by risk, including the risk of incomprehension."
Creating requires taking a scary leap. You can't worry about whether the work is good, bad, indifferent, critic-proof, or even understandable (at first) to others. Just write it as you yourself feel it and see it--the best way to achieve originality.
