Get opinions

It can be hard to critique your own work, may be a story or poetry, so after you’ve done an initial edit, try to get some friends or an editor group (there are plenty online) to look at your writing for you. You may not like all their suggestions, and you don’t have to take any of them, but you might find some insight that will make your writing better. Feedback is good. Pass your writing around, and ask your friends to critique your work. Tell them to be honest, even if it’s painful. Filter their responses, heeding and ignoring, then edit as you see fit.
