Every author must decide what is important to him or her in an editor, but in these days of electronic communication, honestly I do not think it is important to seek a local editor unless your book is specifically related to something of local interest. Even in that case, you may benefit from the perspective of someone who does not have all the local knowledge it can be easy to presume, so that you can prepare your book for a wider audience.
In return for the sacrifices you must make in order to self-publish, you will gain total control over the project. In addition, any profits from sales of the book will be yours (not just a royalty percentage as with either a traditional publisher or a vanity press), and in some cases it may be the only way of getting your book into the hands of readers. However, there is no getting around the requirement to get the tasks done one way or another.
In fact, Pressfield writes, “Resistance is experienced as fear; the degree of fear equates to the strength of Resistance. Therefore the more fear we feel about a specific enterprise, the more certain we can be that that enterprise is important to us and to the growth of our soul. That’s why we feel so much Resistance. If it meant nothing to us, there’d be no Resistance.”
