When it's time to edit line by line, dear writer, you have to get ruthless with your words. This is the time to trim your sentences to their core essence. It's the time to cut anything unnecessary.
It can be brutal work.
But there's a high in this place, too, and it comes when you realize how elegant and lean your prose can be without any heavy adornment. It's the point at which you discover your words can fly with their lightness of being.
Show them off. Let them breathe. Cut the clutter.
