The Successful Failure, "Not just an Apollo mission"

As i finished reading The Great Gatsby i couldn't help but ask myself, why is this Gatsby so great, he failed. I was looking at Gatsby in the sense that he didn't get the girl, and died how could he have succeeded. Page 6 Nick says " Gatsby turned out all right at the end; it is what preyed on Gatsby,what foul dust floating in the wake of his dreams", in this passage two words stand out to me immediatly, preyed, and dust. When i think of dust i think of something that has been neglected for a long time, for example Gatsby left his relationship with Daisy in order to become a successful well to do man like Tom. By doing this dust collected on what was once a love, and when Gatsby tries to cleanse the dust from the past he comes to a harsh reality that the dust, the past is unable to be altered. I saw this as Gatsby's one huge flaw through the entire book, this contributed to many of his other flaws, but he seemed to always be looking for that answer to fix the past and make Daisy fall in love with him again. Yes, Gatsby did live part of the American dream, he went from rags to riches, but he never lived his Dream. When he and Daisy first met it was love, Daisy's marriage to Tom is not out of love but rather of security, in order to counter this Gatsby attempts to offer Daisy the same thing love of money to fill the void of their love that had been lost.
