每个数学问题都有一个解决方案；你只需要找到正确的视角。
Every mathematical problem has a solution; you just need to find the right perspective.
——《致鲁赛尔函》（1906年11月8日）
To be what we are, and to become what we are capable of becoming, is the only end of life.
真相不在言语中，而在它们之间的空白里。
写作是一种乐观的行为。如果你觉得它不重要，你就不会费心去做。
历史不仅仅是过去的事情，它也是现在的镜子。
I prefer to buy stocks that are not widely followed by analysts.
