To avoid wimpy writing, attend to the details. I already talked about avoiding weasel words like some, few, or many in favor of specific numbers or quantities. The same applies to vague nouns: flower, tree, shrub, car. Tell the reader it’s a rose, an elm, an English boxwood, a Ford. Consider how to make chair, house, dog, cat, etc. clearer for the reader. In choosing your specifics, choose your details to further plot, character, tone. Build power one detail at a time.
