One of my passions is Asian languages, one being Japanese in particular, because the values are embedded in the very structure of the language.
There's one Japanese word which brought a lot of clarity in my journey called "IKI-GAI", in short "Life Purpose" or "Life Worth".
It's interesting as it's broken down into 4 sections which involves some major areas of life. If we're able to hit all 4 of these sections on a particular pathway/activity of our calling, we're ultimately able to feel our 'worth', therefore fulfilment.
There was a great quote, by a psychiatrist called Kobayashi Tsukasa regarding IKIGAI
