My audience target will be people who are close to me, like my family and friends. If I target family and friends first as my audience, they could point out my mistakes to me, without me or them taking any offences, and then I could quickly correct those mistakes. They could give me some ideas that I could put in or add. Once my target audience approves of my book, I can then target a bigger audience, like giving it to a book publisher who then (if they approve) will publish it. Once it is out, I could tell my family and friends that my book is published, and that they could then spread the news to their friends or to whomever they choose.
