Guard well your spare moments. They are like uncut diamonds. Discard them and their value will never be known. Improve them and they will become the brightest gems in a useful life. - Ralph Waldo Emerson
好好利用你的空闲时间。它们就象未经加工的宝石,若丢弃了,其价值将永远无从知道;若进行精雕细琢,它们就会成为有价值的人生中最闪亮的宝石。 - R·W·爱默生( 1803-1882,美国诗人、作家、哲学家)
