C.g. Jung said this quote

The biographies of great artists make it abundantly clear that the creative urge is often so imperious that it battens on their humanity and yokes everything to the service of the work, even at the cost of health and ordinary human happiness. The unborn work in the psyche of the artist is a force of nature that achieves its end either with tyrannical might or with the subtle cunning of nature herself, quite regardless of the personal fate of the man who is its vehicle. The creative urge lives and grows in him like a tree in the earth from which it draws its nourishment.
