I have a good friend who is a big-time business guy. One of his pet sayings is, "Data drives decisions." In a bottom-line world, you can't depend on sentiment, heart, hope, dreams or desire. Those all may factor into starting a business. But if the business is not making a profit, and you have hard data showing you why, you either change course or go under.
principles, and came up with 5 absolutely unbreakable laws. I stand by them. They are the foundation for creating your own "set of practices" for self-publishing success.
For example, the primary law is, "Write the Best Book You Can." The set of practices you design to make it so might involve craft study, writing, feedback, writing, finishing, revision, craft study, coffee, more writing. Plans are unique, but the writer who pursues a strategic and thought-out approach to getting better is more likely to win in the end.
