IF- Proverb

Paul Claudel said: "Our only duty is to be happy" (quite inspiring...), so here my little illustration, which also tries to contain a sentence from Miguel de Unamuno: "Jamás desesperes, aun estando en las más sombrías aflicciones, pues de las nubes más negras cae agua limpia y fecundante".
Something like: "Never despair, even in the darkest affliction, as from black clouds falls clean and fertile water".

Have a nice day!
