Take a moment to imagine how you will feel when your work is published. Anything that you think will make you uncomfortable or ill at ease…get rid of it. Lose anything that makes you cringe, anything you think is questionable. If you are writing about someone you know in real life and are worried that you are being too mean or maybe you will feel bad and regret it, change or get rid of it. But, at the risk of confusing you entirely, I have also found that sometimes the pieces I write which cause me the most pain and embarrassment are the pieces others like best. Sometimes it is by working through areas of personal discomfort that you stumble to where your own growth is taking place.
