Plenty of authors land here on our site before they've even written a book. Maybe you've just started the writing process, or maybe you've been writing for years and just can't seem to finish (or even stay focused on one single book idea). In any case, you are here because you need something to help you choose what to write and self publish.
Dog Ear Publishing has helped thousands of authors self publish their books. Sometimes all an author needs to get started is an idea. Write about what you know, write about what you love, write about things that you know other people are interested in and things that you are passionate about.
No matter what the topic - just write!
