回复：双弓安可弯,两弓弃一弓,制导可上天,发射下金城. （一中文词

Jim Rogers有句话我很认同：“我们中的大部分人，没有接受过把注意力集中在单一目标上的训练，持续五年、十年或二十年，放弃其他每件事情去完成它，但这是成为一个奥运会冠军、一个世界级的外科医生或一个基洛夫芭蕾舞演员所必须的要求。当然，这也可能是白费工夫。你所犯的一个错误，可能会让你前功尽弃。古语是千真万确的：有志者事竟成。你想做什么都能做得到，但不可能做到所有的事。培根说‘有妻小者难成大事’。把家庭放在第一位的人，不可能成为世界级的长跑选手，甚至不可能跑出3.5英里。赚你的第一个1000万美元，写一部伟大的美国小说，或骑摩托车环游全世界，这样的目标需要全身心的投入。”

Trial translation:
The majority of us does not have the training to concentrate on the single goal, continuing five years,a decade or two, give up the all other things to accomplish it. It's the necessary requirements to become an Olympic champion , a world-class surgeon or a Kirov ballerina. Of course, this may also be a waste of effort. Once you committe a mistake, you may come to naught. The old saying is true: where there is a will, there is a way. Whatever you want to do, you may be able to do it, but it is impossible to do all things. Bacon said, 'those who have wives and children are difficult to accomplish a big task'. Who place first his family can not become a world-class distance runner, or even impossible to run 3.5 miles, make his first 10 million dollars, write a great American novel, or ride a motorcycle around the world, this goal will require the input of whole energy.
