on Just Publishing Advice:
After all the time it took you to write it, you now want to sell your new book.
Self-publishing a print book or ebook is easy. All you need to do is upload your book cover and interior text file. Within 24 hours, it’s on sale.
However, many new authors rush into publishing without giving much thought to how they will convince readers to buy the book.
The only way to self-publish a new book and have a reasonable chance of success is to plan well ahead. What you do before you publish is always far more effective than what you do after.
