Welzer describes a societal development where ending projects, habits, or life designs becomes increasingly difficult. Despite the evident negative consequences of growth and blind faith in progress, we cling to outdated structures and ways of thinking, manifesting in areas like extended working lives and fossil fuel dependence.

The ability to end things is essential for a successful life and sustainable future. Only those willing to end things can begin anew and face present challenges. Welzer advocates for conscious engagement with one's own finitude and calls for breaking free from modern society's optimization logic.

Welzer recommends writing an 'obituary for oneself' to give life meaning and direction. This exercise helps reflect on personal values and priorities and live more consciously. Engaging with one's mortality enables focusing on truly important aspects of life and actively shaping one's path.
