If you’ve ever had to proofread anything that you’ve written, be sure that you hand the job over to someone else. Even that isn’t foolproof (no pun intended). Get two people to do the job. With my first book, I actually thought I could read and pick up the typos, awkward sentences, printing mistakes. Ha! I missed multiple places that would have been obvious to anyone with any eyesight at all. But not to the person who wrote the words. You see what you meant to write, not actually what is on the page. If you don’t follow any advice at all, follow this maxim. DON’T DO YOUR OWN PROOFREADING.
