My ability to proofread increases by 1000% after I hit “Submit”.
this is often because when you’ve submitted something (like fanfiction to ao3) it will be in a different font, size and framing than in your word processor. The text will look different in the new environment so your brain stops skipping what looks familiar (like a typo that has been there since the beginning).
So, tip: revise your work in a different font and size. I guarantee you’ll catch more typos and mistakes than otherwise.
For all my writers (ones I follow and the ones that thankfully follow me)
