El día más desperdiciado es uno sin reír. NICOLAS CHAMFORT, ESCRITOR

The most wasted of all days is one without laughter.

The most wasted day of all is that on which we have not laughed.

The most wasted day of all is that on which we have not laughed

El día peor empleado es aquél en que no se ha reído

A day without laughing is a day wasted.

It’s too bad if a heart lacks fire,
and is deprived of the light
of a heart ablaze.
The day on which you are
without passionate love
is the most wasted day of your life.

A day when you haven't danced, you haven't lived.

A day without laughing is a day wasted

A day spent without the sight or sound of beauty, the contemplation of mystery, or the search of truth is a poverty-stricken day; and a succession of such days is fatal to human life.

Sir, I look upon every day to be lost, in which I do not make a new acquaintance.

That was the day without a dawn.

My disappoint is immeasurable, and my day is ruined.

La vie est pavée d'occasions perdues.
