When Bell invented the telephone in 1876, President Rutherford said, "That's an        invention, but who would ever want to use one of them?" In the 1940s, another young        named Carlson took his idea to 20 corporations,        some of the biggest in the country. They all turned him down. In 1947 — after seven long years of rejections! - He        got a tiny company in New York, the Haloid Company, to        the rights to his invention. Haloid became Xerox Corporation we know today.
Character cannot be        in ease and quiet. Only        experiences of trial and suffering can the soul be strengthened, vision cleared, ambition inspired and success       .

And remember, the finest steel gets sent through the hottest furnace(熔炉). A        is not one who never fails, but one who NEVER QUITS!
