我们进步的考验不在于我们为那些拥有很多的人增添更多,而在于我们是否为那些拥有太少的人提供足够。
The test of our progress is not whether we add more to the abundance of those who have much; it is whether we provide enough for those who have too little.
Quality is never an accident; it is always the result of intelligent effort.
Judge a man by his questions rather than by his answers.
