When I first began writing fiction, I had many of the same questions. The best advice I got was that I should write down the bones and then go over and over them, adding flesh to them. You might not write in sequence but add on what occurs to you as you read again and again. One of the most important things you need to do is figure out the point or purpose of your story. If you don't know where you're going, you probably won't get there. Hope this helps.
