Obviously I can't, and shouldn't, start developing more stories. So, what do I do with these new future novels?
What I actually do is I have a single word document saved on my DropBox account so I can edit it anywhere I have a computer.
This actually works better for me as I'm an avid keyboard user.
I can easily go back, read the ideas I have and decide a few things:
1) Is it a good idea? If not, get rid of it. 2) Can it be combined with another idea? 3) Is it something I SHOULD write about?
These are things I need to figure out every time I open the file. What is good about using a .doc file is I can highlight and delete very quickly or make any annotations whenever I need.
Write it down
One thing I used to do was the take a pad of paper and jot down my idea. This gives you a tactile recording or our idea. A physical sketching. While this does give you a "hands on" approach, to me it was messier and not as useful. Doesn't help I have terrible handwriting.
So, pick your poison. But don't lose your ideas. You never know, they could end up being your masterpiece.
