把这一句，留给此刻的你

But without deeper reflection one knows from daily life that one exists for other people--first of all for those upon whose smiles and well-being our own happiness is wholly dependent, and then for the many, unknown to us, to whose destinies we are bound by the ties of sympathy.

但是，不需要深入思考，我们就能从日常生活中了解到，我们是为别人而存在的——首先是为那些我们的幸福完全依赖于他们的微笑和幸福的人而存在，其次是为那些我们不认识的人而存在，他们的命运与我们的同情息息相关。

— Albert Einstein 爱因斯坦
