A good world needs knowledge， kindliness， and courage； it does not need a regretful hankering after the past or a fettering of the free intelligence by the words uttered long ago by ignorant men.
一个良好的世界需要知识、善良和勇气；它不需要对过去的后悔，也不需要被无知之人长时间前说过的话所束缚的自由智慧。
A single seed can change the world.
种植蔬菜就是种植希望，每一粒种子都是对未来的承诺。
