People who try to write books are often hoping to make lots of money, not realising that actually there's really no money in it except for a minuscule minority of people. They also have no concept of what grindingly boring hard work it is. I see alleged 'books' where it is clear that the author has simply clanked it out and sent it off, not realising that successful authors go over and over their text ad infinitum (and throughout the long editing process) honing and refining it, and taking on board well-intentioned and well-informed advice, usually from their long-suffering editors. Does anyone realise that the words by, for example, Jeffrey Archer that they read are, shock horror, often not the actual words that he wrote but those of an editor? Publishing a book is often, contrary to popular belief, an exercise in the crushing of ego and the emptying of the wallet.
