My husband has been reading Boris Johnson‘s book The Churchill Factor. Whatever you think about Boris Johnson or Churchill, the book is a good read. In the acknowledgements section, Johnson cites Churchill on writing books.
Writing a book is an adventure. To begin with it is a toy and an amusement. Then it becomes a mistress, then it becomes a master, then it becomes a tyrant. The last phase is that just as you are about to be reconciled to your servitude, you kill the monster and fling him to the public.
