I have observed the business that G-d gave humans to be concerned with:
He brings everything to pass precisely at its time;
He also puts eternity in their minds,
but without humans ever guessing, from first to last,
all the things that G-d brings to pass.
Thus I realized that the only worthwhile thing there is for them is to enjoy themselves
and do what is good in their lifetimes;
Also, whenever people do eat and drink and get enjoyment out of their wealth,
It is a gift from G-d.
