Compelling leaders, as Aristotle might say, have three qualities that they express through three "languages":
Agility (or "Logos"). This language is about reading situations and getting things done... he needs to demonstrate that he is a learner.
Authenticity (or "Ethos"). Followers need to know that you have deep values and dreams, and they need to hear you speak about hope. They also want to know that you are animated by some big beliefs. Authentic language comes from the heart.
Empathy (or "Pathos"). Caring for people... Do you listen carefully? Are you helpful?
