You do have a book inside you, and it does want to come out! If you allow me to be your midwife, we'll get it out -- healthy, robust, and ready to take on the world!
And if you don't want it to take on the whole world, I'll show you how to take on just that portion of it that suits you -- your niche market, your family, or your affinity group.
I have a passion for helping people who want to write a book. On this site, you will find tons of resources -- stuff to help you with narrowing your topic, choosing your audience, outlining your book, doing the writing, publishing, and marketing -- and more.
Look around. (Maybe start with my blog.) Contribute where you can. There's a lot here.
