It has existed throughout our human history for various reasons: Adam’s punishment from the god, then humans worked for survival; followed by maintaining their family, money making, finding one’s own passion and serving for others / world, etc. The type of work has evolved from hunting, farming, religious act, art and product making, mass production and service, digital work, etc. (and you might have heard it will change drastically in near future!)
Except 7-8 hours unconscious time of sleeping (if you are lucky and conscious enough to get that much), most people work more than half of our given time (be it at home or office). We work to live, achieve something meaningful and/or probably be happy. It is our nature and that’s how it has been.
However, our energy has a limit and we cannot keep using. Let’s see the mechanism of work and energy, and how to live happily without getting burnout.
