The Japanese are among the longest-lived people in the world, due in part to ikigai—a philosophy of fulfilment, joy, and mindfulness—often embedded in their approach to careers, family relationships, and hobbies. We can all benefit from it, and so neuroscientist Ken Mogi identifies five key pillars to ikigai: starting small, releasing yourself, harmony and sustainability, the joy of little things, and being in the here and now. No matter what your situation may be, Mogi explains how we can all tap into this distinctly Japanese zest for life.
