The most precious thing for a person is life, and life is only once for everyone.

The most precious thing for a person is life, and life is only once for everyone. A person's life should be spent in this way: looking back on the past, he will not regret for wasting his time, nor will he be ashamed for being mediocre; when he is dying, he can say: "My whole life and all my energy have been dedicated to The most magnificent cause in the world - the struggle for the liberation of all mankind."

人最宝贵的就是生命，生命对于每个人来说只有一次。人的一生应该这样度过：回首往事，他不会因为虚度年华而悔恨，也不会因为碌碌无为而羞愧；临终之际，他能够说：“我的整个生命和全部精力，都献给了世界上最壮丽的事业——为解放全人类而奋斗。”
