人生最大的荣耀不在于从不跌倒，而在于每次跌倒后都能站起来。

"The only way to learn mathematics is to do mathematics."

"There is no such thing as a new idea. It is impossible. We simply take a lot of old ideas and put them into a sort of mental kaleidoscope. We give them a turn and they make new and curious combinations."

我不需要理由去坚韧。

让世界改变你，然后你改变世界。
