Pantsers (a term used by NaNoWriMo) like to jump right in and write whenever inspiration strikes! Some famous pantsers include Stephen King and Ernest Hemingway. This kind of writer prefers to do less planning up-front; King, for example, believes that ideas go “stale” the longer you sit on them, and that diving right in is the best way to keep the creativity flowing.
If this style sounds like you, you might benefit from the resources on this site geared towards pantsers, such as spur-of-the-moment prompts and creative exercises. But feel free to explore all resources and use whatever feels right for you. Writing is a very individual process, and there’s no one way to do it!
