Sketch a timeline of events that will happen. Brainstorm scenes using sticky notes and move them accordingly. Create character sketches beforehand, so you have a better understanding of key players in your novel.
Reading articles, essays, or books might inspire you to write your own. Besides, Google is your best friend.
At some point, that first draft needs to be written. Unfortunately, it won’t write itself. So pick up a pen or open your word processor of choice. Grab an idea and run with it.
Take a deep breath. You don’t have to get it right the first time. Try to silence your inner editor for now. You can always make a draft better, but you can’t if it doesn’t exist yet.
