Did you know that research has shown that brainstorming on your own is actually more productive than brainstorming in a group? While there are times that a team can help generate a lot of ideas, don’t discount the idea of brainstorming on your own. With a clear process and a little bit of practice, you can brainstorm like a rock star! (Assuming rock stars brainstorm. Which they probably don’t. Well, maybe about song ideas.)
Brainstorming is definitely a tool you need to be an author.
