If you know what you want to write, and need a push to get started, consider writing to a timer. Set a timer for 5 minutes and write as fast as you can for the whole 5 minutes on your topic of choice. This can be a useful way to quickly draft ideas without getting too caught up in revising or editing. It can be a useful technique for jumping into the writing, too. It’s a good way to get out of the editing/revising/perfectionistic mindset and into the place of pure creation. Try it for yourself.
