Plotter

Simply put, a plotter is someone who plans out their novel before they write it. There are various levels of plotters. Regardless, outlining their novel before writing is extremely important to these writers.
In fact, it's essential to the writing process. It's what keeps their story structure in tact, and it is also crucial to have if they want to finish their manuscript.
Plotters value knowing what's going to happen in their story before writing it. They want clarity. A plan gives them energy and intention, and it saves them a lot of time when they do write their book (and also when they revise!).
