What's My Purpose?

Whoa. This whole blog. It's too much like work. Time to ask, What's my purpose here? This blog comes about after lots of suggestions to promote the books I've completed. Even if the book is published by a traditional publisher, the author still gets to promote it. I've made up a newsletter to send to clients. And incidentally, the books will be available. Well, who else will I interest in the books? Otherwise, why bother to publish them? So there could be an element of promotion in this blog. An element of promotion. Is it to serve or is it to be 'served'....to serve the vanity of it all? Then again, if no one knows of the books, the alternative is that they end up in my hard drive. This blog is based so far on the long version of the newsletter--the versions I didn't use so I could keep the newsletter short. And if it's to only promote books...that is "work"...it's not the fire of the Gods. I even have a sense of....of.... just to view the purpose
