We also discussed the challenges of editing our own work - something most writers face at some time. I've always thought that it's a tougher call than doing the original writing.
That's almost a process of letting it come out but in the editing you have to think about and decide on each word you use. And killing what we like about our writing because it doesn't work is a hard act to carry out.
It's something that I've struggled with over the years and I hope I'm better at now. What I try and hold in my mind when I'm editing is this question.
How much can I take out without it affecting what I really want to get across.
In one of my business courses I was advised to cut a twelve page piece to eight. My mind shrieked can't be done but of course it could be and was all the better for the pruning.
All good writing has a shape and that's what we need to find in the editing process.
