君子之交淡如水,小人之交甘若醴。
The friendship of a gentleman is light as water; the friendship of a small person is sweet as honey.
"Words are the voice of the heart."
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.
