As a writer, how to go from a Pantser to a Plotter / Outliner

Pantser:
A "Pantser" is a writer who writes by the "seat of their pants," meaning they don't plan or outline their story ahead of time. They dive into writing with little to no predetermined structure, allowing the story and characters to develop organically as they write.

Plotter/Outliner:
A "Plotter" or "Outliner" is a writer who meticulously plans and outlines their story before starting to write. They create a detailed roadmap, including character arcs, plot points, and story structure, which guides them throughout the writing process.
