Writing is hard labor. Nobody can do it for you, no matter how brilliant you are or how wonderful your concept is. It may be awful or confusing, but it's still a book, and many published writers haven't fared much better... The main thing is to keep going. The most successful books are the ones that not only speak to an audience, but also resonate with them. If you have something to say and the way to say it, then don't worry about your background or experience. Just start writing and see what happens. Books aren't written by experts in their fields. They're written by people who are expert at creating stories that appeal to readers. If you can craft a good story that speaks to people's needs and desires, they will read you regardless of your background. Writing is about communication, and good writers find ways to communicate important ideas through engaging characters using clear language. That can be done by anyone with a passion for storytelling. The only person who can tell if you've hit on something great is you. Have fun with it! And don't forget to read and learn from others as you go along.
