The secret of success (The key to success) is not so much money as a strong will. A great man is one who has a strong will and an indomitable spirit. In other words, if a man does not have a strong will to win (get) the final victory¹, he will never succeed in his life. He is no more than a failure.

It is quite obvious that there is no difficult thing (nothing difficult) in the world. if you make up your mind to do it, you will certainly accomplish² your end. That stands to reason.

成功的要诀不是金钱而是一个坚强的意志（用not so mush... as）。一个大人物是一个具有坚强意志和不屈不挠精神的人。换句话说，如果一个人没有坚强意志去获得最后胜利的人，他终其一生永远不会成功。他只不过是（用no more than）一个失败者。

很显明的世界上并没有难事。如果你下定决心去做它，你一定会达到目的。那是显而易见的。
