I recently realized that I've been in the self-publishing game for over a decade. I wrote my first eBook sometime in 2002 (I've been erroneously saying 2004 for years). The reason this is important is, the longer you do something, hopefully you get better at predicting what makes you successful at it.

It wasn't until 2010 that I started to make some real money selling eBooks online. That year, I earned over half my annual income from eBooks I wrote and self-published. I still own/operate an SEO writing company, but if I never picked up another client, I could make a full-time living writing and self-publishing my own eBooks.

In February, my sister uploaded a short fiction eBook and sold 541 copies in just 25 days – mostly on Amazon. She earned over $1,100 dollars. The eBook was a short romance of only about 65 pages; a "novelette" she called it. And, it only took her approximately a week to write. She priced it at $2.99, netting $2.09 from Amazon for every copy sold.
