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

岁月会在额头上留下痕迹；而抛却热忱，则让灵魂长满皱纹。忧愁烦恼，恐惧焦虑，自疑畏缩，一定使心灵颓废，意气如灰。

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

年华流失只将皱纹留痕于皮肤，然而激情的冷却却将皱纹留痕于灵魂。忧烦，惶恐，自我放逐定使心灵扭曲，使春之朝气灰飞烟灭。
