You cannot hope to build a better world without improving the individuals. To that end, each of us must work for our own improvement and, at the same time, share a general responsibility for all humanity, our particular duty being to aid those to whom we think we can be most useful.
你不能希望在不改善个人的情况下建立一个更好的世界。为此,我们每个人都必须为自己的改进而努力,同时也要为全人类承担共同的责任,我们的特殊职责是帮助那些我们认为我们最有用的那些人。
The challenge is to make the ordinary extraordinary.
