According to Osho, yes: creativity flowers when you accept, rather than deny, your neurotic part. Repression breeds hypocrisy, fear and paralysis; acceptance brings those energies into awareness, where they can be transformed and used creatively. Freud's denial made him defensive and divided; your conscious, honest embrace of your contradictions frees energy, restores integrity, and allows authentic no's and yes's to guide original expression.
If you accept the weird, worried parts of you instead of hiding them, their energy can help you create.
