Some advice on writing?

Writing is the best way to improve your skill, but reading has its benefits as well. You'll be able to expand your vocabulary, learn how different styles of writing can evoke different emotions, and also learn how to shape different 'voices' for your characters. Worrying about creating your own style of writing is a legitimate concern, but there is nothing new under the sun, and anything you eventually write will be similar to something else out there. That isn't to say that you can just mimic someone's style and call it good, but you shouldn't place it as your first concern when learning the basics.

In my first writing class at college, we spent the first half of the semester just practicing writing scenes. He would give us premises to write about, like two people meeting at a restaurant or someone getting back home from work, and wanted us to make it as accurate to life as possible without going overboard on detail. Eventually we moved on to plot concepts, making a skeleton of a story, then going on to complete a whole shory story. You could follow the same sort of regimen to get some practice.

Are there any colleges close to where you live? If they have any creative writing classes, see if you can buy any used copies of their instruction books and learn from them, or take the classes if you can. Getting daily practice in writing, especially with a professor to help along the way, will definitely help.

Jam it back in, in the dark.
