a sudden downpour

The challenges I faced while starting a new life in a new city brought to mind the change of the seasons.
These initial challenges have already faded, however new challenges are beginning.

A gusty wind cannot last all morning,
and a sudden downpour cannot last all day.
Who is it that produces these? Heaven and earth.
If even heaven and earth cannot go on for ever,
much less can man.
