In my house we have no dishwasher, or conversely you could say we have two dishwashers, and we both pay rent. When we have used up every cup and plate in the house and can go no longer without washing, it is the cutlery that is the most heartbreakingly tedious part of the task.
Self-editing is the cutlery of writing.
Many writers hate to edit their work, especially longer pieces of writing, and a lot of new writers are tempted to skip it altogether. That is a great decision to make if you are a) a genius, or b) trying to increase your collection of rejection letters. For the rest of us it is not a good tactic.
Aside from the typos and homonyms that you will leave behind, there will be superfluous words, repeated words, tense changes, point of view slips or even character name cock-ups (yes guilty, I had Brent and Brant in a story and they were actually the same person). The only way to find all these problems is to edit your work, edit it again, put it down, let it rest, mature, ferment and then… edit again.
Many writers set time limits on how long they need to wait after finishing a piece before they can send it out to ensure they have distanced themselves enough to give it a proper edit. Others actually set numbers of edits required (7 I’ve read for a lot of novel writers). When starting out you don’t need to be that regimented, but more than one edit is a must, and at least 24 hours of sitting time is also mandatory! But more on both accounts will only improve your final product.
Don’t sell yourself short, it takes a lot to finish a story, so don’t undermine all that hard work by putting it out there before it is ready. You can burn the perfect market or worse, you can have your substandard work published! It is much better to have a clean manuscript that is ready to send out a few weeks later, than a flawed one that is ready to go now!
Happy editing (and give thanks for your dishwasher),
