Just thought I'd write a little note about book marketing.
My experience is that authors spend too much time and money asking other people to do their marketing for them. That's a big mistake. There's a place for paying people for services rendered, but no one can market your book like you can. No one. Not me, not some hot-to-trot publicist, not some Internet marketer. You should always be the best salesperson for your book.
Marketing doesn't need to take all your time. Devote a half hour or an hour a day to it. Hire people to do the grunge stuff, but the key phone calls, key letters, key emails should be made by you. Written by you. Impassioned by you.
