"It’s puzzling that there isn’t a stronger tradition of “user testing” for writing. Occasionally I’ll give a friend something I’ve written and implore them, “Please circle anything that makes you feel even slightly unhappy for any reason whatsoever.” Then I’ll ask them what they were thinking at each point. There are always “bugs” everywhere: Belaboring of obvious points, ambiguous phrases, unnecessary antagonistic language, tangential arguments about controversial things that don’t matter, etc."

This is called an editor. They're invaluable!
