This extract from Myself When Young is specifically about writers and writing. (Interestingly, she presents it as if from a male perspective. She was of a generation where this tended to be the norm, but I wonder whether there is more going on than that. Daphne seems to have had some ambivalence about her sexuality. She is said to have wished she had been born a boy, and wrote more than one book from a male perspective.)
The child destined to be a writer is vulnerable to every wind that blows. Now warm, now chill, next joyous, then despairing, the essence of his nature is to escape the atmosphere about him, no matter how stable, even loving. No ties, no binding chains, save those he forges for himself. Or so he thinks. But escape can be delusion, and what he is running from is not the enclosing world and its inhabitants, but his own inadequate self that fears to meet the demands which life makes upon it. Therefore create. Act God. Fashion men and women as Prometheus fashioned them from clay, and, by doing this, work out the unconscious strife within and be reconciled.
