You cannot hope to build a better world without improving the individuals. To that end, each of us must work for his own improvement and, at the same time, share a general responsibility for all humanity.
如果不改善个人，就无法希望建立一个更美好的世界。为此，我们每个人都必须为自己的进步而努力，同时为全人类承担共同的责任。
Life is 10% what happens to you and 90% how you react to it.
Do not let your fire go out, spark by irreplaceable spark.
飞得越高，摔得越重。
The real problem is not whether machines think but whether men do.
