美国作家塞谬尔:
Youth is not a time of life; it is a state of mind. It is not a matter of rosy cheeks, red lips and supple knees. It is a matter of the will, a quality of the imagination, vigor of the emotions; it is the freshness of the deep spring of life.
青春并非生命的一段旅程,而是一种心境;非粉颊、红唇和柔膝,而是远大的理想、磅礴的想象、旺盛的激情;是清新的生命源泉不断涌动。
Youth means a temperamental predominance of courage over timidity, of the appetite for adventure over the love of ease. This often exits in a man of 60, more than a boy of 20. Nobody grows merely by the number of years; we grow old by deserting our ideas.
青春意味着勇气战胜怯懦,意味着勇于进取,不屑平凡。如此锐气,二十年后有之,六旬男子则多见。年岁有加,并非垂老,理想的放弃才真正意味着垂垂老矣。
