...if you are writing without zest, without gusto, without love, without fun, you are only half a writer. It means you are so busy keeping one eye on the commercial market, or one ear peeled for the avant-garde coterie, that you are not being yourself. You don't even know yourself. For the first thing a writer should be is-- excited. He should be a thing of fevers and enthusiasms.

Ray Bradbury (2015). “Zen in the Art of Writing”, p.12, HarperCollins UK
