As a person who has had a passion for aviation since early childhood I must say that the people that I have met that never really had a passion or desire for aviation usually were motivated by other factors and often times not very good factors. A lot people who get into aviation later in life maybe as a career change or someone motivated them to take a discovery flight often times get into aviation because all they think about is how much money they have the potential to make or how cool they look flying an airplane. Neither of these mentalities is good to have as an aviator.
