The concept of purpose has existed in many cultures. One particular culture that stands out of this is Japanese Culture. Japanese have a term called Ikigai, which means the 'reason to live.'
The Ikigai concept unites the joy of Life with a sense of Purpose. The term is a combination of the Japanese words 'iki' ('to live') and 'gai' (reason)—thus 'reason to live' or, in other words, your Purpose. For the Japanese, Ikigai is more of a way of Life, a journey, than a destination you target.
