"The act of writing is an act of optimism. You would not take the trouble to do it if you felt it didn't matter."

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.

教育不能改变世界。教育改变人。人改变世界。

Never stop learning, because the world never stops changing.
