Kokoro, by Natsume Soseki (paragraph #145)

然し我々は眞面目でした。我々は實際偉くなる積でゐたのです。ことにKは強かつたのです。寺に生れた彼は、常に精進といふ言葉を使ひました。さうして彼の行爲動作は悉くこの精進の一語で形容されるやうに、私には見えたのです。私は心のうちで常にKを畏敬してゐました。

translation

But we were serious. We were actually on the verge of becoming great. K was especially strong. Born in a temple, he always used the word diligence. It seemed to me that his deeds and actions could all be described by this one word of diligence. I was always in awe of K in my heart.
