In other words, luck is rooted outside the natural order of the natural world. There is no cause and effect action in relation to luck because luck is an entity outside of reality that intercedes to change something for the better by chance. The inherent flaw found within this theory is obvious: nothing exists outside the natural world and nothing exists outside the normality of physics. There is no such thing as a supernatural world nor is there such a thing as a paranormal world.
Luck simply does not really exist, but is often invoked as the reason behind seemingly unexpected success or the alliance of events that happen to work out in a persons favor. The concept of luck is mocked in the statement, The harder I work, the luckier I get. How does that quotation mock the concept of luck? If a boxer trains hard everyday, runs five miles a day, spars hours a day, eats the proper diet everyday, etc and wins a match, there will be those pundits who may say it was a lucky win.
The boxer can respond, Yes, the harder I work, the luckier I get. In other words, luck was not the factor behind the boxers win. The boxer created the lucky environment through the cause and effect relationship of putting the hours in to make himself a great boxer. A boxer is one such example, but one could also use the example of a politician running a successful campaign or a scientist who discovers a major breakthrough that was initially unexpected.
Again, while there can be flippant responses to the success of these people to the tune of luck having been on their side, the reality is that any paranormal interference of an entity of luck. Again, luck is not a disruption of a logical chain of events it is the predictable outcome of a common chain of events. The irony of the quotation The harder I work, the luckier I get effectively flaunts the silly pretense that something as abstract as luck actually exists.
