Victorine Lieske put together a great blog post showing the slow build many Indie authors go through with their sales. No, not every Indie publishes and starts selling a lot of books. A lot don’t even sell more than a few books… at first.
It goes to show that patience, diligence and persistence really does make a difference. Oh and adding new material. I noticed a lot of authors got a bump in total sales when they released something new.
Remember it’s a marathon, not a sprint.
