Previously, I posted some writing rules.
Here is another selection from that pdf. This time, it's Orwell's Questions.
What am I trying to say?
What words will express it?
What image or idiom will make it clearer?
Is this image fresh enough to have an effect?
Could I put it more shortly?
Have I said anything that is avoidably ugly?
(When I typed this list, I almost typed What image or idiot will make it clearer? I guess idiots sometimes make everyone else look better, so maybe that works just as well!)
What questions do you ask yourself when you are writing?
