The pursuit of peace and progress cannot end in a few years in either victory or defeat. The pursuit of peace and progress, with its trials and its errors, its successes and its setbacks, can never be relaxed and never abandoned.
Dag HammarskjoldNever let success hide its emptiness from you, achievement its nothingness, toil its desolation. And so...keep alive the incentive to push on further, that pain in the soul which drives us beyond ourselves...Do not look back. And do not dream about the future, either. It will neither give you back the past, nor satisfy your other daydreams. Your duty, your reward - your destiny - are here and now.
Dag Hammarskjold
