I just read a helpful article From NY Book Editors about some fundamentals for turning your self-publishing into a full-time job. This is not a guarantee or a get rich scheme, but they just cover a couple of basics that all aspiring self-published authors should know:

1. Treat it as seriously as a full-time job, not a hobby
2. Stick with one genre to build your niche
3. Invest in marketing
4. Have an author platform
5. Nurture your fanbase
6. Write a series
