我们进步的考验不在于我们是否为那些已经拥有很多的人增加更多,而在于我们是否为那些拥有太少的人提供足够的帮助。
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.
The only thing that can bring you happiness is yourself.
Great companies don't just sell products; they solve problems.
