That should be on a Tile

Jan Steen is known not only for his work as a painter, but
also for his expressions and sayings. The most striking
examples are: “Life in the brewery”, “Like the old sang, so the
young squeak” and “A household of Jan Steen”. They are
often used as a warning that you should set and follow a
good example.
In the Netherlands they call these sayings ‘Tegeltjeswijsheid’
or ‘tile wisdom’, referring to the custom of writing sayings on
a Delft Blue tile. What original wisdom, saying or warning can
you come up with? Write it in beautiful letters on the back of
a beer mat and decorate it like a tile from the time of Jan
Steen.
