1. Writing for the wrong reason. The most common wrong reason to write a book is to make a lot of money. Statistically, you’re heading for disappointment. Instead, you should write a book for good reasons such as you have something valuable to say, you have a cause you want to further, or you want to meet the intellectual challenge of writing a book.
2. Not hiring a professional copyeditor.
3. Designing your own cover. The cover is one of the most important marketing pieces for your book, so hiring a great graphics designer is money well spent.
4. Not building your marketing platform in advance. Self-publishing is not a serial process where you can write a book and then worry about marketing it later. You need to start building a marketing platform as soon as you start writing because the process takes a year. You should already have thousands of followers on social media on the day that you ship.
5. Using a word processor other than Microsoft Word.
6. Inadequately testing your ebook. Do not assume that if your ebook looks right on one platform that it will look right on all the others. You can’t even assume that if your book looks good on a Kindle tablet that it will look good on a Kindle app. The only way to truly know is to examine your book on each platform.
7. Selling only an ebook version.
8. Depending solely on social media and word of mouth. Google+, Twitter, Facebook, Pinterest, and LinkedIn are powerful and inexpensive marketing methods, but old-fashioned PR is still necessary.
9. Getting feedback from writing community prior to finalizes. There are always people out there who know more than you do and who are willing to help for the intrinsic value of helping a fellow human being.
10. Having only one plan. There are at least three plans to getting your book published: Plan A is to find a traditional publisher; Plan B is to self-publish; and Plan C is to implement Plan B in order to attract a traditional publisher and reinstate Plan A. There is no right and wrong; there is only what works for you and what doesn’t, so be flexible.
