Youth is not like a new garment which we can keep fresh and fair by wearing sparingly; youth, while we have it, we must wear daily; and it will fast wear away. John Foster
Youth is like those verdant forests tormented by winds: it agitates on every side the abundant gifts of nature, and some profound murmur always reigns in its foliage. Georges Maurice de Guérin
Youth, like the aloe, blossoms but once, and its flower springs from the midst of thorns: but see with what strength and to what height the aloe-flower rises over them. Walter Savage Landor
