“Should happiness and success be hidden, in view of the misery and poverty around. Would it be a sign of selfishness and un-intellectual behavior, if we admit to a pursuit of happiness? Could it, on the contrary, not work out as a motivation and an incentive? When giving voice to our happiness, could it not be perceived as a positive challenge? Could happiness not be contagious and become a salutary infectious syndrome? A beneficial infection. ( "Happy days are back again" )”
