"The supreme good is like water,
which nourishes all things without trying to.
It is content with the low places that people disdain.
Thus it is like the Dao.
In dwelling, live close to the ground.
In thinking, keep to the simple.
In conflict, be fair and generous.

In work, do what you enjoy.
In family life, be completely present.
When you are content to be simply yourself
and don't compare or compete,
everybody will respect you. "
