Hello all, as the title says I'm new to writing. I've been looking around the forums, and looks like a great place to learn grow. I have had idea for a novel for about a month or so now. I've begun putting it on paper, but every time I start writing, I get a flood of new ideas. The plot more or less stays the same, but I think the story-line is becoming too long. Too grand. Too over the top. How do you add interesting subplots and characters, while still staying focused on the main story?
