In the end, we are all alone, and that is the fundamental condition of human existence.

衡量生命的尺度是思想和行为，而不是时间。

Sometimes we get sad about things and we don’t like to tell other people that we are sad about them. We like to keep it a secret. Or sometimes, we are sad but we really don’t know why we are sad, so we say we aren’t sad but we really are.

——临终时对孔祥熙说，1925年3月

The only way to do great work is to love what you do.
