perusing art journaling sites, i came across this great post called "How to Kill Your Innate Creativity" by paper artist Debra Cooper. it was a good reminder of how we can kill our writing.
How to Sabotage Your Writing (all of which i've done)
-- spend all your writing time thinking about writing, buying books about writing, and coming up up with new stories but never write.
-- compare your story to everyone else's (and wonder if it will fit into the market - whatever that is).
-- try to keep everyone else in mind when you write instead of keeping yourself in mind.
-- think about all the negative reviews and critiques and never remember the positive feedback.
-- believe that everything you write should be great.
-- expect that you'll find your plot in the first draft and try to make the first draft perfect.
-- expect that writing will be easy and that there will be no resistance.
