Here are some ideas on how to begin writing your novel. In this video, I focus on outlining, the hook, inciting incident, first plot point, first pinch point, midpoint, second pinch point, second plot point and climax. Also, you might want to check out James Patterson's "Master Class" and Ellen Brock, freelance editor.
Here's a little video I made on why I think outlining your novel is super important...and I wish I had started doing it earlier. To any of you writing a novel out there, I hope that this helps!
