The author of How Steel Is Made, The Children of the Storm Girl, famously said: "The most precious thing of man is life. Life only once for a man. Therefore, a man's life should be spent like this: when he looks back on his past, he will not regret his time because of his vain time. Nor shame for his inaction; this search, when he dies, can say that I have devoted my whole life and all my energy to the most magnificent cause in the world, the struggle for the liberation of mankind.
