I've had this idea for a story for over, like, 2 years, and yet, I can't find a way into it. So far I've got maybe 7 pages into it but my mind just doesn't seem to want to release the information. What makes it worse, I keep getting bombarded with other story ideas. I tried to just start working on one of the others for a little while and come back but my mind keeps creeping back. My charactors( and there are many) are screaming to be let out of my head( they are starting to get on each others nerves), and I keep getting scenes at random from the random books! Please help me!

You don't necessarily have to write the story from beginning to end.  If a particular scene is dominating your mind, write it out.  That will probably spur you to write other scenes.  If they're not in sequence, that's fine, you can always link them together later.  Eventaully you'll find you have most of the story written and you can start doing rewrites to make sure you iron out any inconsistencies.

My first draft of a novel I wrote straight through from beginning to end, but for that one I pretty much knew in advance exactly how things were going to play out.  But from the 5 or 6 other ideas jumbled in my head, I'm just writing the scenes that are most forefront in my head at the moment.  Eventually one of those books will be close enough to complete that I can focus solely on that one to edit and polish it up.

Well Selena, the one piece of advice that I can give is something that I've read and heard about quite a bit.  That is " just sit down and write it".  Of course that's easier said than done.  The one rule that I try to follow is that if I truly don't feel like writing at a particular time, I simply do something else.  I don't want my "hobby" of writing to become a chore.  Writing is the one unique creative outlet that I have and I want it to be something that I always look forward to instead of something that I dread.  Maybe if you try writng in a different environment you'll get the inspiration and disipline that you need.  I try writing in different parts of the house, or the local coffeehouse, the park, down at the beach, anywhere to get a different mindset.   I don't know what your story is about, but if it's something that you can or were involved in, if you can get back into the scenario on a personal level, this may give you the push to get the words on paper.  I myself am writing a story based on a tragic incident at my wokplace so everyday at work since then gives me little doses of inspiration.  Good luck, dont beat yourself up.

You might like Randy Ingermanson's Snowflake Method, if you want to organize it a little more (or a lot more). I was at a point a while back where I knew the story was good, but wasn't sure that I was going to be able to write it. This method helped me out A LOT. Check it out here, if you want.
