When describing nature, a writer should seize upon small details, arranging them so that the reader will see an image in his mind after he closes his eyes. For instance: you will capture the truth of a moonlit night if you'll write that a gleam like starlight shone from the pieces of a broken bottle, and then the dark, plump shadow of a dog or wolf appeared. You will bring life to nature only if you don't shrink from similes that liken its activities to those of humankind.
Anton ChekhovIf in the first act you have hung a pistol on the wall, then in the following one it should be fired. Otherwise don't put it there.
Anton ChekhovWhen you describe the miserable and unfortunate, and want to make the reader feel pity, try to be somewhat colder - that seems to give a kind of background to another's grief, against which it stands out more clearly. Whereas in your story the characters cry and you sigh. Yes, be more cold. ... The more objective you are, the stronger will be the impression you make.
