I like A.A Milne. Apparently his agent was alway telling him to write something other than what he was writing. If he was working on a children’s book they would tell him to do a detective story instead, and when he did that a bit later they would say he needed to write a humorous story instead and so on. So, he concluded that “the only excuse which I have yet discovered for writing anything is that I want to write it, and I should be as proud to be delivered of a telephone directory con amore as I should be ashamed to create a blank verse tragedy at the bidding of others.”
