当他回首往事的时候,他不会因为虚度年华而悔恨,也不会因为碌碌无为而羞耻 的英文版本怎么说?

Man's dearest possession is life. It is given to him but once, and he must live it so as to feel no torturing regrets for wasted years, never know the burning shame of a mean and petty past; so live that, dying, he might say: all my life, all my strength were given to the finest cause in all the world -- the fight for the liberation of mankind.
