Thought about writting a book but don’t know where to start?
Why don’t you start a blog? Every time you post, think of it as part of a chapter. When all is said and done, print all the posts. You’ve got a book!
Later you can use the blog to promote the book, asking people to give reviews about the chapters. You can have a book trailer and put on Google, Youtube and others to reach thousands of people. And why not have a podcast where you read some chapters?
