美国大作家马克·吐温年轻时热衷于发明创造。他一生中,在各种新产品、新发明上的投资多达50多万美元。但那些项目却没一个成功,他的投资都打了水漂。后来,马克·吐温心灰意冷,发誓永远不在“新奇玩意儿”上浪费金钱了。一天,一个年轻人登门拜访这位大文豪。来访者胳膊底下还夹着一个怪模怪样的东西。 The American writer Mark Twain was keen to invent when he was young. In his lifetime, he invested more than half a million dollars in various new products and new inventions. However, none of those projects succeeded, and his investment was overshadowed. Later, Mark Twain was disheartened and vowed to never waste money on the “novelty stuff.” One day, a young man came to visit the great writer. There was a strange thing under the visitor’s arm.
