“One thing we know for sure is that change is certain. Progress is not. Progress depends on the choices we make today for tomorrow and on whether we meet our challenges and protect our values.”

“But today our very survival depends on our ability to stay awake, to adjust to new ideas, to remain vigilant and to face the challenge of change. The large house in which we live demands that we transform this world-wide neighborhood into a world – wide brotherhood. Together we must learn to live as brothers or together we will be forced to perish as fools.We must work passionately and indefatigably to bridge the gulf between our scientific progress and our moral progress. One of the great problems of mankind is that we suffer from a poverty of the spirit which stands in glaring contrast to our scientific and technological abundance. The richer we have become materially, the poorer we have become morally and spiritually.”

“We cannot justify mentally shifting into neutral and failing to exert our efforts to progress intellectually. Whether or not you are in school, the challenge is the same. We should continue learning throughout our lives.”

“We yearn for tomorrow and the progress that it represents. But yesterday was once tomorrow, and where was progress in it? Or we yearn for yesterday, for what was or what might have been. But as we are yearning, the present is becoming the past, so the past is nothing but our yearning for second chances.”

“Whether we succeed or fail in life depends on our ability to conquer the challenges in our opportunities, and to discover the opportunities in our challenges.”

“We yearn for tomorrow and the progress it represents. But yesterday was once tomorrow, and where was the progress in it?”
