Designing a Life of Sustainable Well-Being

 What does it mean to live a life you can proudly call your own—even in the face of mortality? Inspired by Yamaguchi Shu’s vision of life as a strategic project, this post introduces a conceptual model that connects personal goals, time resources, and life management strategies. It offers a practical lens for designing a life rooted in sustainable well-being.
