For me, writing is therapeutic. With all the crap that occurs during the day, I can just sit and begin analyzing what interesting things happened during the day and turn it into a story.
In order to write, I need a few things:
At times, okay a lot; I develop writers block. Its annoying. I know what I want to write, but I can't quite work out the details. I'll have a beginning and maybe five minutes of an end scene or just a small scene to work from and then I'm stuck. To break this block, I introduce a soundtrack. Music is very effective for me when I write.
If its an action scene, I'll listen to Rock or Hip-Hop. If its a scene that is sad or emotional, instrumental music is usually my go to or anything along the lines of the Garden State soundtrack.
Once everything is drafted, I'll type my story and perform another round of editing. It's long and tedious, but this process help to get my writing the way it's meant to be.
