You don't have to paint a picture that the person did a exceptional awe-inspiring things despite impostor syndrome. You can write the article that says normal people run into this, it's Not Just You, and at no point does the article need to look like it's trying to prop anyone up. It can be about an average person, not even yourself, and it's still valuable!
