It’s a good idea to proofread your writing. It’s more than a good idea; it’s imperative. We appear careless or unintelligent because of sloppy writing. Here are a few tips to help you make your writing as good as it can be:
1. Proofread out loud and slowly. I can’t emphasize this point strongly enough. If you proofread silently and quickly, you will read what you think you wrote, not what you actually wrote. You don’t need to proofread in a stentorian voice, just loudly enough so you can hear yourself over whatever noise is going on around you. You may need to leave the room to be able to read your writing so you can hear it.
2. Proofread for specific things. If you know you have a problem with verb tenses or parallelism, proofread one time only for that. Then do it again to look for other problems.
3. If you’ve revised your writing as you type, proofread to see if by changing your prose you have left out words or kept words in that shouldn’t be there. We commonly forget to check for errors caused by rewriting.
4. Proofread one time specifically to check your punctuation. Again, do this slowly.
5. Pay attention to spell check and grammar check alerts. Occasionally, they are incorrect, but for the most part you will need to fix something.
