In fiction, we need to insert other elements close to the beginning. We introduce our major character as early as possible. Unconsciously, readers identify with the protagonist—male or female—because reading is a vicarious experience. For ten minutes or ten hours we become someone else as we turn pages.
Be sure to make the time period clear. Unless you tell us differently, we'll assume it's the present. But don't have people fight with swords or radioactive beams without making readers know the era.
Don't underestimate the importance of place. We're all creatures who occupy space on the earth and we want to know where a story takes place. Place is like an anchor. Once we know we're in Sydney, Australia, or Rye, New York, we can enjoy the story instead of wondering, "Where is this taking place?"
Good novelists know the important elements of a superb beginning—and they include them.
