This means using specific, detailed language. When you mean cold, don't just say cold, but describe for readers the frost curling on a mustache or the visible breath of an antelope. Make it so a reader can feel cold without you ever using the word cold itself. Say what you mean. Mean what you say.
Writing is an act of bravery.
Readers must understand your meaning without equivocation. Give the meaning with a straight needle. Find your voice. You have something to say worth saying. Your readers can decide what to read.
