There are five things in this life that are needed by every living person.
1) The need to breath air
2) The need to eat food
3) The need to drink water
4) The need to pee/poop
5) The need to rest/sleep
Anything else is purely a want.
Wait a minute…
I don’t really WANT to go to work. But do I need to go to work? No, it’s not actually a need, unless I want to pay my bills. Still, do I really need to do that, or is that a want after all? I don’t want too, not in any sense of the definition, but I know what will happen if I don’t.
Humans; the only lifeform that must work, to earn, to pay, to live.
