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 mater of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life.

• 青春并非人生的一段时间，它指的是一种心态；青春的表现不在于满面红光，嘴唇红润，腿脚灵便，而在于意志的坚强，想象力的品位，感情的充沛，青春是生命之深泉的清澈常新。
