on Writing Forward:
Writing a book is a big deal. It takes a lot of time and effort, especially if you want to do it right, which means creating something that people will find entertaining or useful and then polishing, marketing, and promoting it.
It all begins with an idea — a concept. It might start with a few characters or an intriguing plot you’ve dreamed up. It might start with an audience you want to write for or a topic you want to explore.
Many writers start writing as soon as an idea strikes. This approach works for some people, but for most of us, it’s a road to nowhere. If we attempt to write a book every time we get a good idea, we constantly leave previous ideas half-finished. If we don’t stop to think about whether the idea is viable, we may get in over our heads or write a book that’s unpublishable or unsalable due to market saturation or lack of interest.
