Book marketing should be a planned process, an art if you will.
If writing and publishing a book is like giving birth to a child, then book marketing is like rearing it.
Marketing starts even before our books are published.
Never use the phrase: 'buy my book' - ever.
Don't give up before you get off your feet. Put the time in to learn what you can, build relationships, and develop quality content.
It's never too early to start marketing your book.
