Youth is not a time of life; it is a state of mind;
青春不是年华，青春是一种心境。
it is not a matter of rosy cheeks, red lips and supple knees;
它不是红颜，朱唇，柔膝；
it is a matter of the will, a quality the imagination,
它是一种深沉的意志，一种恢弘的想象，
a vigor of the emotions;
和饱满的热情；
it is the freshness of the deep springs of life.
它是我们生命之泉在不息的涌动。
Nobody grows old merely by a number of years.
岁月有加，并未垂老。
We grow old by deserting our ideals.
抛弃理想，方堕暮年。
