Many moons ago I saw the above status, and it got me thinking. Why should I work? Why does anybody work?
A very high level view is, people work to satisfy their hunger. For some it's for satisfying the basic need of body, hunger of food. For some it's hunger of brain, they can't sit idle, they need to do something.
But it's not that simple, it's not a choice between these two. Everyone prioritizes these hungers depending of different parameters of their life. For some getting a day's meal is priority, so they will do any type of work they can get as long as their basic need is satisfied. For some, they already earn enough to satisfy their basic needs, so they look for a kind of work which will give them mental satisfaction.
This is how I look at it.
