The quality of preferring societal benefit in order to suppress overall burden by minimizing one’s own burden while even compromising NEPs (personal) in accordance with the endurance level and working to squeeze societal burden by an efficient strategy in line with the capability level
As living creatures, we have needs to fulfil in order to comfort ourselves. When these individual needs combine, the resultant is the societal burden (the burden of needs applied by the individual to the society) (environmental & physical burden is also added).
