Before you submit your freshly-written book to your editor or proofreader, do a search through the document and locate every instance of the words very, a bit, slightly, lightly, kind of, sort of, really and maybe. Delete them. Then read through those sections to see if they need those weak modifiers. On rare occasions they might. Some dialog works better with them. But most of the time, they aren’t needed. Not even slightly. Really.
