I’ve been thinking about how much of self-publishing happens after the book is finished. Writing the book is one thing, but getting the right people to actually discover it is a completely different challenge. For those of you who have already published, what’s one thing you learned about marketing, visibility, reviews, Amazon, social media, or getting readers that you wish you had known before launching? I’d be interested to hear what actually worked for you and what turned out to be a waste of time or money.
