The book promotion module I have stresses the need to rely on your family and friends to give the initial impetus to one's book. The idea being there needs to be a seed snowball formed that can pick up size as it rolls down the hill. Ultimately, of course, it will have to stand or fall on its own. As Paul McCartney says, or almost says," I'll need a little help from my friends."
In the meantime, I hope I am not singing out of key.
