Writing a story without an outline, discovering the plot as you go, guided by instinct and curiosity rather than a predetermined plan.
Pantsing means diving into a story with little or no outline, letting the characters and situations guide where things go next. The name comes from the phrase "flying by the seat of your pants," which is exactly what it feels like. Instead of mapping out every plot point in advance, you write your way into the story and figure things out as the words hit the page. Many beloved authors, including Stephen King, are proud pantsers.
Pantsing can produce some of the most surprising, alive-feeling fiction because the writer is genuinely discovering the story in real time. That sense of spontaneity often translates directly to the reader's experience. It is also a fantastic way to beat the paralysis that comes from over-planning, because you never get stuck trying to perfect an outline you have not even started writing yet.
Pick a character with a clear want, like a barista who desperately needs to leave town. Write for fifteen minutes without stopping or planning ahead. When you hit a fork in the story, choose the option that surprises you most. Afterward, read what you wrote and highlight the two or three moments that feel most alive.
