This insight also suggests the best way to find motivation at work is to find our own higher purpose. If we know what we value most and what is most meaningful to us, then we know what we can work on that serves our higher purpose.
Some of us are lucky and we have the flexibility to ensure that our work directly serves our higher purpose (versus, say, earns enough of a living to support it or keep one's family sheltered, fed, educated and have affordable access to healthcare). I'd wager that is a small majority of humanity. What should the rest of the world do?
