I’m betraying the Pantser camp. Pantsers are dirty and smelly, and they throw baby carrots at people for no reason. Jokes aside—after nearly two years of editing my novel and outlining new projects, I’ve come to prefer meticulous planning over off-the-cuff writing.
For those who don’t know, a Pantser is one who writes “by the seat of [his or her] pants” without planning ahead, whereas a Plotter is one who outlines the novel’s story and narration to a significant extent before writing the first chapter.
Writing as a Pantser just created more work for Future Me.

Readers might get stuck in the crotch and never get to the other pant leg.
Three years ago, I started a manuscript with minimal planning. I had some ideas for the world and setting, created psychological profiles and backgrounds for a few main characters, and then I let those characters lead themselves through 80,000 words of meandering hi-jinks. My first draft, more appropriately referred to as a “junk draft” or “draft zero,” suffered from significant structural problems which has required a lot of editing.
Lack of planning leads to excessively lopsided story arcs.
In a misguided attempt to write a commercial YA with a literary feel, I wrote my first chapters as slice-of-life vignettes with the intent of creating a sense of normalcy before crazy junk happened (note: there’s nothing with a commercial-literary hybrid, I just didn’t do it right). I let my characters do whatever they wanted, and they did a whole lot of nothing for too many chapters (albeit with some fun banter). This problem extended into much of the “rising action” portion of the MS which, essentially, rose too slowly.
Characters, like children and actors, need some direction.
To be clear, even as a Pantser, I often had conclusions in mind as soon as I opened up a new plot line. The problem was I’d have two or three conclusions and take too long to decide on one of them.
Outlining reins in the characters and helps build a proper arc.

So much sexier.
Knowing a majority of the plot points, both major and minor, it’s easier to adjust the pace of individual scenes so they properly contribute to the pace of the overall novel. So, the rising action has only minor dips from the resolutions of subplots rather than momentum-breaking pitfalls which results in an anti-climactic ending.
“Double rainbow . . . what does this mean?” Well, it should mean something.
Ideally, everything described in a novel should tie into the overall plot, character development or world building—preferably all three. The more you know of the whole story, the better you’ll be able to emphasize the importance of the individual pieces by linking them together. A lot of these connections can be established and elaborated during the revision process, but it saves so much time if you plan things out a bit earlier as opposed to retroactively squeezing things in.
So, for my future novels . . .
Having more writing experience, I can probably be a much better Pantser if I choose to write without outlining. However, I’m definitely going to try to be a Plotter for my next project or two.
