Here are some specific ideas to help you get started. First of all and most importantly:
You must understand the core challenge you are facing.
You are facing the overwhelming challenge at the start of writing a story that many writers face and run from. You have all of this information compiled and in some ways you feel as if it is too much. It overwhelms the mind about how you would organize it. (This is an emotional challenge -- for more read my article Great Debate: Can You Learn To Write From a Book?)
Next, there are some specific things to focus on to distract your mind from the overwhelming nature of the work.
Focus on Specifics to Distract the Mind
- Think In Scenes
- Write Extremely fast draft
Let's go over each of those and see how they might help you:
Think In Scenes
Understand that readers want to see your story played out on the "movie-screen" of their minds. This is when the words transform from words into images that the readers "see".
Now, instead of thinking about all of your research, go ahead and imagine a scene that would show your character in some type of trouble that s/he needs to work out of.
Character's Self-Concept Can Create Tension
Additionally, if you understand your character's self-concept, you may even provide tension as the character has to do something that goes against what she believes of herself. You can read more about the power of self-concept in my article : Easiest Way To Get Fiction Ideas: Self-concept Against the World
But allow me to show you how you might do that here.
Suppose your character is kidnapped and taken to a hotel in the desert. Later he escapes into the desert and the kidnapper is following him. He's trapped and the only way out is through a very small opening at the base of the mountain. However, your character is extremely claustrophobic (afraid of small places). Now, there is some tension which will grab your reader.
Write Extremely Fast Draft
Instead of focusing on all of that overwhelming research,
focus on writing the shortest possible version of your story
Imagaine if you were going to write a flash-fiction version of your story. How might you do that?
Tell only the shortest snippet of what would communicate your story to a FTR (First-time Reader). How might you do that?
Scene 1 Early Monday morning Henry is eating his egg & cheese breakfast sandwich when he steps into the lobby of his bank. Someone
pushes in behind him and he drops his sandwich. Before looking at the
rude person Henry blurts out, "You idiot. What's the rush, fella?"
The man, in a long black coat and a hat pulled down over his brow,
turns, pulls a gun out of from the coat and points it at Henry. "I
need to make a quick withdrawal. And you'll do just fine."
Scene 2 The bank robber shoved Henry into the back of the green sedan, looked at the guy behind the wheel and said, "Drive. We've got
about 1 minute head start." The driver gunned the engine and Henry
slammed into the back seat then rolled into the floor before he could
brace himself. The sound of sirens blared through the air and the
chase was on.
Scene 3 Back at the hideout, the driver asked the robber, "what we going to do with the dead-weight" and he jerked his thumb toward
Henry. "We'll drive out to the desert, kill him and dump him."
Get Something Done
If you really do this, you'll get something done. You're brain will relax from all the overwhelming information. Plus, you'll get the benefit to see where things work or dont' work very quickly in your story.
Hope this helps.
Good luck and get started.
Keep on learning, keep on writing.
