Observation by telling us whether there is anything that you would sacrifice your life for - not for another person - but for an idea or principle. Explain why that principle is so worthy. Be specific. "For Justice" or "For Peace" doesn't count. What concrete kind of just society? What sort of peaceful world? Make this individualized and personal!
