The fourth enemy within is worry. We' ve all got to worry some. Just don' t let it conquer you. Instead， let it alarm you. Worry can be useful. If you step off the curb in New York City and a taxi is coming， you' ve got to worry. But you can' t let worry loose like a mad dog that drives you into a small corner. Here' s what you' ve got to do with your worries： drive them into a small corner. Whatever is out to get you， you' ve got to get it. Whatever is pushing on you， you' ve got to push back.
The fifth interior enemy is overcaution. It is the timid approach to life. Timidity is not a virtue， it' s an illness. If you let it go， it' ll conquer you. Timid people don' t get promoted. They don' t advance and grow and become powerful in the marketplace. You' ve got to avoid overcaution.
Do battle with the enemy. Do battle with your fears. Build your courage to fight what' s holding you back， what' s keeping you from your goals and dreams. Be courageous in your life and in your pursuit of the things you want and the person you want to become.
我們的勇氣並非生來就有，恐懼也是如此。有些恐懼可能來源於你自身的經曆、他人的講述或從書上讀到的東西。像半夜兩點獨自走在城中的危險地段，這樣的一些恐懼是可以理解的。隻要你學會避免這些情況，就不必再惶恐地生活。
即使是最基本的恐懼，也會讓我們的雄心壯誌徹底粉碎。我們的財富與情感皆會被恐懼所摧毀。如果不加以節製，它就會毀掉我們的生活。恐懼是蟄伏於我們內心的眾多敵人之一。
讓我跟你說一說我們麵臨的其他五個內在敵人。第一個敵人是冷漠，在它襲擊之前，你必須先下手為強，否則打著嗬欠懶洋洋地說：“啊哈，就這樣吧，我就隨波逐流吧。”這是多麽可悲的弊病！你永遠無法漂至山頂，這就是隨波逐流的問題所在。
猶豫不決是我們麵臨的第二個敵人。它是一個竊賊，會偷去你的機會和事業。它會偷走你獲得美好未來的機會。舉起你的劍，同這個敵人決鬥吧。
內在的第三個敵人是懷疑。的確，正常的懷疑論仍有保留的餘地。你無法相信一切，但也不能疑心重重。很多人對過去、未來、彼此以及政府心生猜疑，對所有可能的事物和機會也持懷疑態度。最為嚴重的是，他們連自己也不放過。我要告訴你，懷疑會摧毀你的人生和你獲得成功的機會。它會使你的賬戶出現赤字，讓你的心靈幹涸。懷疑是敵人，驅趕它，消滅它。
第四個敵人是擔憂。我們都會有所擔憂，但不要被擔憂的情緒所控製。相反，讓它成為你的警鍾。擔憂也會有好的用途。如果你走在紐約的人行道上，有出租車朝你開來，那你就得擔心了。不過，你不能讓擔憂像隻瘋狗似的將你逼到牆角。你應該利用擔憂，並將它們驅至牆角。無論什麽想抓住你，你都要抓住它。無論什麽攻擊你，你都要予以還擊。
第五個內在敵人是過度謹慎。它是一種膽怯的生活方式。膽怯是一種疾病，而非美德。如果你放任它，它就會支配你。膽怯之人是不會有所發展的。在經濟市場中，他們難以進步、成長，也難以強大起來。你必須要避免過於謹慎。
向這些敵人開戰吧。向你的恐懼發起攻擊。鼓足勇氣去對抗那些阻礙你的事物，與那些阻擋你實現目標與夢想的事物戰鬥吧。勇敢地生活，勇敢地追求你想要的一切，勇敢地成為你理想中的人。
冷漠、猶豫不決、懷疑、擔憂、過度謹慎，這是束縛人們發展的五大殺手，也是人們所麵臨的最大的敵人，假如你不想整日惶恐不安、遇事猶豫不決、做事謹小慎微、待人冷漠無情，那麽就盡快驅逐這些敵人吧，它們是阻止你前進的最大障礙。

Getting Aroused
奧裏森·馬登 / Orison Marden
"How' s the boy getting on， Davis？" Asked Farmer John Field.
"Well， John， you and I are old friends，" replied Deacon Davis， as he took an apple from a barrel and handed it to Marshall' s father as a peace offering； "we are old friends， and I don' t want to hurt your feelings； but I' m a blunt man， and air going to tell you the truth. Marshall is a good， steady boy， all right， but he wouldn' t make a merchant if he stayed in my store a thousand years. He weren' t cut out for a merchant. Take him back to the farm， John， and teach him how to milk cows！"
If Marshall Field had remained as clerk in Deacon Davis's store in Pittsfield， Massachusetts， where he got his first position， he could never have become one of the world' s merchant princes.
But when he went to Chicago and saw the marvelous examples around him of poor boys who had won success， it aroused his ambition and fired him with the determination to be a great merchant himself. "If others can do such wonderful things，" he asked himself， "why cannot I？"
It had then only about eighty-five thousand inhabitants. A few years before it had been a mere Indian trading village. But the city grew by leaps and bounds， and always beat the predictions of its most sanguine inhabitants. Success was in the air. Everybody felt that there were great possibilities there.
Many people seem to think that ambition is a quality born within us； that it is not susceptible to improvement； that it is something thrust upon us which will take care of itself. But it is a passion that responds very quickly to cultivation， and it requires constant care and education， just as the faculty for music or art does， or it will atrophy.
"What I most need，" as Emerson says， "is somebody to make me do what I can." To do what I can， that is my problem； not what a Napoleon or a Lincoln could do， but what I can do. It makes all the difference in the world to me whether I bring out the best thing in me or the worst—whether I utilize ten， fifteen， twenty-five， or ninety percent of my ability.
Everywhere we see people who have reached middle life or later without being aroused. They have developed only a small percentage of their success possibilities. They are still in a dormant state. The best thing in them lies so deep that it has never been awakened. Great possibilities of usefulness and of achievement are， all unconsciously， going to waste within them.
