During your writing, have you ever stumbled upon Mary Jane? Who is she? Why, she’s an absolutely beautiful character (forgive the unnecessary adverb). Everything about her is flawless – her hair, her makeup, her clothes. She’s so smart, she never makes a mistake. Because she’s the epitome of perfection, she always gets along with other characters. Why, she has the answers for every situation. I suggest we all watch out for her. Why’s that? It’s simply this. Mary Janes are so perfect, readers cannot identify with them and, worst of all, they’re boring.
A Few Tips on How to Avoid Mary Janes
Give Characters Weaknesses/Flaws/Fears
One of my favorite authors is C.S. Forrester. In his series about the fictional Napoleonic War naval hero, Horatio Hornblower, Hornblower sometimes gets seasick. This adds to his humanity. One wouldn’t expect a naval hero to get seasick, but Captain Hornblower does. Although I’ve never been seasick because I grew up on the Gulf Coast and did lots of saltwater fishing in my younger years, my friends who do get seasick can identify with him.
Let Our Characters Make Mistakes
If they’re our story’s protagonist, mistakes go a long way toward gaining reader sympathy for him/her. If they’re the villain, readers will rejoice at the villain’s error.

Hercule Poirot may be one of the mystery genre’s greatest detectives. Want to know how he died in Agatha Christie’s last Poirot novel, Curtain? He made a mistake many people, unfortunately, make. He died of a heart attack because he didn’t take his heart medicine
Give Our Character a Unique Physical Appearance

A character may walk with a limp due to an old injury. Or, perhaps, he’s missing a finger from a chainsaw accident.
Mary Janes may wear petite size dresses and always promenade in designer clothes. However, although a more believable female character may wear a size petite dress in our story, she might also wear lots of frumpy clothes and battered tennis shoes.
A Final Word
It’s important to spend quality time thinking about our characters. Make an outline of their strengths and weaknesses and portray them as original, and believable, as we can.

And hey, watch out for Mary Jane! She lurks everywhere within manuscripts and in the pages of certain books.
