For, after a certain distance, every step we take in life we find the ice growing thinner below our feet, and all around us and behind us we see our contemporaries going through.
人生走过某段路以后,每迈一步,都会觉得脚下的冰更薄一些;四周和身后,同代人正一个个坠入冰下。
— Robert Louis Stevenson · Virginibus Puerisque, and Other Papers · Æs Triplex —
