In the middle of difficulty lies opportunity.
In science, we try to explain what we don't understand. In mathematics, we try to understand what we can't explain.
从挫折中获得智慧、变得坚强,意味着你比以往任何时候都更有能力生存。只有在逆境来临的时候,你才会真正认识你自己,了解身边的人。这种了解是真正的财富,虽然是用痛苦换来的,但比我以前得到的任何资格证书都有用。
The more you try to forget, the more you remember.
