It says in the Parasha of Ki Thabo, "And all these blessings shall come upon you and overtake you, if you listen to the voice of the L-rd your G-d".
Sometimes a person is so blessed by G-d that whatever he does he succeeds in, even if logically his business venture should fail. A story that illustrates this well is the story of Timothy Dexter who, in the 18th century, exported two shiploads of coal from Virginia to Newcastle in England, which was a famous coal producing town. Everyone was expecting to hear of his ruin because of this foolish act. When his ships arrived in England, a miners' strike was in progress. Dexter sold all his coal for a handsome profit.
Even if a person runs away from success, if G-d wishes him to have it, success will run after him as it says, "all these blessings shall come upon you and overtake you". But, as far as the Jewish people are concerned, we must know that there is a condition. Our blessings are dependant on the keeping of the Torah, as the Pasuq (verse) says, "if you listen to the voice of the L-rd your G-d".
