Substitute "damn" every time you're inclined to write "very;" your editor will delete it and the writing will be just as it should be. ~Mark TwainI'm with Mark on this one. Eliminate "very" from your writing vocabulary and your writing will only improve. There is no difference between "red" and "very red" and no difference between "fast" and "very fast." Or should I say that the difference is only in your mind. You think in terms of the difference, but your reader doesn't know how much faster a car becomes in your mind when you say "very fast" rather than "fast.
So... try it out. For a chapter or two in your book, avoid using "very." It's one good way to tighten your writing.
