Youth is not entirely 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 temper of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life.

• 青春不是年华，而是一种心态；不是玫瑰般的脸庞，红润的嘴唇和敏捷的双腿，而是坚韧的意志，丰富的想象力，以及无穷的激情；青春是生命深处的一股清泉。
