"Writing a novel is like making love, but it's also like having a tooth pulled. Pleasure and pain. Sometimes it's like making love while having a tooth pulled."
I love the images conjured up by this quote. Pain and pleasure is basically what life is all about. Why should creative work be any different? We experience both pain and pleasure while doing creative work — painting, writing, singing or dancing. Hopefully, you experience more pleasure than pain. One cannot exist without the other and both teach us something.
