诗人是一个种下一棵树然后坐在它的树荫下的人。

我不是为评论家做音乐，而是为那些能感受它的人。

数学的本质在于它的自由。

Old paint on canvas, as it ages, sometimes becomes transparent. When that happens it is possible, in some pictures, to see the original lines: a tree will show through a woman's dress, a child makes way for a dog, a large boat is no longer on an open sea. That is called pentimento because the painter 'repented,' changed his mind. Perhaps it would be as well to say that the old conception, replaced by a later choice, is a way of seeing and then seeing again.

成功不是终点，失败也不是致命的，重要的是继续前进的勇气。
