Some of the findings referenced regarding when you were born influencing your outcomes are included below (many borrowed from Malcolm Gladwell; I would highly recommend his book Outliers for more on this subject).
Wealthy folk in the United States
8.16% of U.S. births happen in June, only 6.13% of CEOs were born in that month
8.75% of the U.S. population born July,, only 5.87% of CEOs were born in July
Historians looked from Cleopatra and the Pharaohs and combed through every year in human history ever since, looking in every corner of the world for evidence of extraordinary wealth, and almost 20 percent of the names they end up with come from a single generation in a single country: of Seventy-five richest people in history, 14 are Americans born within nine years of each other in the mid 19th century.
In professional English youth academies (aged 16-20 years) 57% of youngsters were born in September, November or December whilst only 14% celebrated their birthday in June, July or August.
In one U17 European Championship, 75% of the footballers were born in a four month window.
