青春不是年华，而是心境；青春不是桃面、丹唇、柔膝，而是深沉的意志、恢宏的想像、炽热的感情；青春是生命的深泉涌流。

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, a vigor of the emotions; it is the freshness of the deep springs of life.

青春气贯长虹，勇锐盖过怯弱，进取压倒苟安。如此锐气，二十后生有之，六旬男子则更多见。年岁有加，并非垂老；理想丢弃，方堕暮年。

（这一句说是含有敏感词，发送不了）,for adventure over the love of ease. This often exists in a man of sixty more than a body of twenty.Nobody grows old merely by a number of years. We grow old by deserting our ideals.

岁月悠悠，衰微只及肌肤；热忱抛却，颓唐必致灵魂。忧烦、惶恐、丧失自信，定使心灵扭曲，意气如灰。

Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul. Worry, fear, self-distrust bows the heart and turns the spirit back to dust.
