There is just one life for each of us: our own.

The line expresses a stark ethical and existential claim: each person has only a single, untransferable life to live, and therefore cannot outsource responsibility for choices, suffering, or moral agency. Read this way, it pushes against living vicariously through others (family, rulers, heroes) or treating one’s fate as something that can be exchanged or substituted. In a tragic framework often associated with Euripidean drama, the thought can also carry a note of urgency and limitation—human beings must act within the confines of one finite life, without the comfort of a second attempt. The emphasis on “our own” underscores individuality and accountability.
