If living means happiness, or something like it, then I would say that there are two categories of things needed for it. One is the prerequisites, such as freedom for need, bordom, illness ( including depression ) and fear etc.. But that only brings comfort, the opposite of discomfort, which simply leads to contentment alone. And the second category is appreciation, which includes appreciation of self, ( attainment ) and appreciation of the world, and its gifts, ( taste ). Surviving is merely to attain the level of comfort, and effort is required to attain happiness.
