Just as there's no right or wrong way to write a book, there's no right or wrong way to publish a book. Traditional publishing works best for some folks, and self-publishing works best for others, and there are pros and cons to each. It's about what works best for you.
This comes down to discernment. What makes sense for the kind of book you've written, the kind of work you do, and your existing or potential audience? What are your goals? What's your time frame? What does the gentle invitation for the publishing of this specific book seem to be?
This is about finding your path. The great news is, it gets to be your own.
