Been trying to do that, somewhat.
But the characters themselves interfere with the writing.
NNB could explain that better than I could, probably.
Isn't it best (my creative writing course talking now), to write up character sketches, like, everything about a character....on a piece of paper (or however many it takes)....get them "out of your head" and onto paper....then just start writing the story....
You have to remember to be the dispassionate, non-judgemental observer and recorder.
If you insist on trying to drive the story in a direction of your choosing, they will be balky and uncooperative.
