如果我们选择了最能为人类幸福而劳动的职业，那么，重担就不能把我们压倒，因为这是为了人类而献身。那时，我们所感到的就不是可怜的、有限的、自私的乐趣，我们的幸福将属于千百万人。我们的事业将永恒地存在，并发挥作用。面对我们的骨灰，高尚的人们将洒下热泪。
If we have chosen the position in life in which we can most of all work for mankind, no burdens can bow us down,because they are sacrifices for the benefit of all; then we shall experience no petty, limited, selfish joy, but our happiness will belong to millions, our deeds will live on quietly but perpetually at work, and over our ashes will be shed the hot tears of noble people.
