Constituents want to see their own hopes in the future the leader describes, so the job is to draw out a vision people hold in common, not to sell one's own. The leader listens deeply to others (including what is not said), makes the vision a cause for commitment rather than a job, answering what people seek in work (integrity, purpose, challenge, growth, belonging, autonomy and significance), and keeps looking forward in times of rapid change, when a shared sense of direction matters most.
