爱是由心灵衡量的空间和时间。
每一个数学问题都是通向更深入理解世界的窗口。
Your time is limited, don't waste it living someone else's life. Don't be trapped by dogma, which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become.
The general will is always right， but the judgment which guides it is not always enlightened.
