Before rushing into the publishing phase, know all of your options!
There are so many out there - self-publishing, traditional publishing, POD Publishers, E-Books, etc. - make sure your choice is the best option for YOU!
Research each of these areas carefully and know what you are getting into before you leap into the project. Understand POD Publishers and the vanity/subsidy press lable; research every step of the process if you intend to self-publish; be aware that you should never, ever pay a traditional publisher or an agent to review your submission.
And remember, no matter what path you take, YOU are responsible for marketing and promotion!
