Yes, writing has rules, just like anything else.
One of the greatest things about writing is that most people can become good, selling writers in only two years.
One of the biggest problems in writing is that most people do it in their spare time and don't get serious enough about it.
Many wannabe writers hide behind the excuse that they didn't learn punctuation and English basics well enough in their formative years.
If that is your situation, most good schools will have brush-up courses available.
Some students will say they are to old to learn new things, but to that I say, "Bah.
Humbug.
" I have no short-term memory, yet I keep managing to learn as long as I apply myself, and I'm closing in on 70 years of age.
If I can do it, you most certainly can, too.
Writing is a hobby that gives everyone a chance to spread his/her wings.
Some people will be better at it than others, but that's okay.
Give yourself permission to not be at the head of the class.
My guess is you won't be at the rear, either.
If you want to learn Short Story writing, a good course will teach you how to set a theme, prepare a plot, target your audience, and choose your point of view.
You will learn how to cast your characters, create good dialog, and use word imagery for settings.
Next, you must learn to build the conflict, cut your verbiage, and perhaps most important of all, learn "Show, Don't Tell".
To learn writing for children (which is not any easier than writing for adults, trust me), you will begin by outlining your story, fleshing out your characters, studying market techniques, building your point of view, Show, Don't Tell, creating good dialog, editing your drafts, polishing your final draft, and creating queries and cover letters.
If you're interested in learning Fantasy writing, you will learn histories of the genre, and subgenres.
You will learn how to find inspiration, create fantasy characters, create a fantasy world, and create the elements necessary to transport your readers to a believable story.
You will learn how to outline, create a spell that will enchant your readers, and mix in magic potions.
You'll learn the difference between fantasy writing, horror writing and sci-fi writing.
Writing will teach you to have a 'tougher skin' so that more advanced students can offer comments on your work.
You will learn to profit by it instead of getting hurt and sulking into a corner.
As a writer, you must have this attitude.
It is one of the few absolutes.
Rejection is a large part of writing, and you should know that going in.
I would leave you with one last piece of advice.
I thought I was the exception to the rule, and that I could skip ahead in my learning because I wanted it bad enough and I had an excellent foundation in English.
I was so wrong.
I skipped the beginning elements and had to go back for them later.
After I had taken a few courses, I realized how they mesh together to make a larger picture, and that skipping any part of the package only caused me grief in the long run.
Start at the beginning and work your way through the courses patiently.
Learn each one well.
Study regularly, listen to your mentors, and do extra homework that is above and beyond the call of duty.
In this way, you will ensure a writing career that has no holes in its foundation, and you will be fulfilled.
