They're a rotten crowd, I shouted across the lawn. You're worth the whole damn bunch put together." Gatsby was great because he had the ability to live in the moment, not thinking far ahead in life other than his search for his beloved daisy, who he very deeply and passionately loved. At the beginning of the novel, "The Great Gatsby", the narrator Nick says that if personality was a series of unbroken gestures. Gatsby was it. Gatsby was the essence of the gesture, of not having the substance of life, but having the cover, the surface. Gatsby's greatness comes from his strong will to earn wealth , his constant desire to capture Daisy's hearth using that and the way his life transformed into a quest for it.
             The life Gatsby created for himself was an illusion. By the same token, the title of the novel refers to the theatrical skill with which Gatsby makes his illusion seem real. He had a charming personality that made people attract towards him. Nick in particular was taken with Gatsby and considered him a great figure. The reader's also can't help but admire Gatsby's brilliance, his romantic idealization of Daisy and his yearning for the future.
             The private Gatsby who stretches his arms out forward the green light on daisy's dock seems somehow more real than vulgar. He is well characterized by the idea that he believed in the green light. "Gatsby believed in the green light, the orgiastic future that year by year recedes before us" narrates Nick. As a man he dreams of daisy, and for a while he wins her too. In a world without a moral centre, in which attempting to fulfil one's dreams is like reviving a boat against the current. Gatsby power to dream lifts him above the meaningless and amoral pleasure seeking of the New York society. Gatsby's capacity to dream makes him 'great', despite his flaws and eventual undoing.
