Turn Simple Ideas into Income: Self-Publishing with Amazon KDP

You create a book once, whether it’s a low-content journal, a children’s story, or a guide, and it can keep earning royalties for years. The hardest part is doing the research to find a niche that sells, but once you hit the right topic, it’s almost like setting up a small passive income stream.
