"Ikigai (生き甲斐, pronounced [ikiɡai]) is a Japanese concept meaning "a reason for being". Everyone, according to the Japanese, has an ikigai. Finding it requires a deep and often lengthy search of self. Such a search is regarded as being very important, since it is believed that discovery of one's ikigai brings satisfaction andmeaning to life. Examples include work, hobbies and raising children.
The term ikigai is composed of two Japanese words: iki (生き?), referring to life, and kai (甲斐?), which roughly means "the realisation of what one expects and hopes for".
In the culture of Okinawa, ikigai is thought of as "a reason to get up in the morning"; that is, a reason to enjoy life. In a TED Talk, Dan Buettner suggested ikigai as one of the reasons people in the area had such long lives."
