"History is not a linear path; it spirals, trapping us in its cycles until we confront its ghosts."
历史不是一条直线；它螺旋上升，将我们困在其循环中，直到我们直面它的幽灵。
The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.
真正的创新来自于对现有问题的深刻理解。
不是要成为最好的，而是要变得比昨天更好。
