[fǎn zhě dào zhī dòng: "To return is the movement of the way."-from Dao De Jing]
Happiness does not depend on how much we have, how famous we are, or how high our social position is. Rather, it depends on how we see ourselves. If we are content with what we have or what we are, we feel tranquility.
In many cases, however, people feel unhappy because they are not satisfied with what they have or who/what they are. So they seek more and more without knowing what will happen tomorrow.
Obviously, in some cases, the issue is the opposite; that is the problem of absolute poverty. If someone is in that dire situation of poverty, nothing is more important than having a basic income that may sustain his/her family.
We should go back to the simple truth that we are small or nothing.
