Unrest of the spirit is a mark of life; one problem after another presents itself and in the solving of them we can find our greatest pleasure.

Our reading
An editorial interpretation.
Restlessness is presented as a sign of being alive. Problems keep arriving one after another, and working through them is where the deepest satisfaction comes from. It reframes constant challenge as a source of pleasure, not just a burden.
