I took a college writing class last semester. Its torturous lack of spaceships and fantastical beings taught me a lot about writing. (Note to colleges: you should allow speculative fiction into your curriculum. It's rather fun.)
1. Essay writing taught me better grammar.
Formal writing requires no broken grammar rules. Learning these rules helped me improve my writing and know when it is okay to break the rules. Hey, sometimes ya gotta break the rules for effect.
2. Essay writing taught me how to macro-edit.
My first drafts were scatter-brained messes. (Well, apparently not when I'm feeling creative or under a strict time restraint.) Editing short non-fiction is great practice for editing long fiction. Trust me.
3. Essay writing taught me how to show, not tell.
If any of you know me, you probably know that I tend to write short. Super short. My longest WIP is currently 41k words. Having a 700-word minimum when I can say the same amount in 500 words is difficult. My problem? I told rather than described. Quickly, I learned to either add more description and examples or add another paragraph (though I got in trouble for doing this instead of sticking to a 3-part thesis).
4. Essay writing showed me to line edit by hand.
There's something therapeutic about writing all over a paper with a blood-red pen. (Until you've edited your entire 41k book with it over a period of 24 hours. True story.)
5. Essay writing showed me I write better under pressure.*
We had to do a few timed essays in this class. This is like NaNoWriMo in an hour and a half with no planning and perfect writing. Somehow, I always got better grades on these essays.
*If I planned before writing.
Have you ever written an essay? Did it teach you anything about writing? I would love to hear your thoughts!
