Nose wings relate to the ability of a person to earn income or generate wealth from multiple sources including paper wealth. Broad nose wings indicate a person has the ability to make money in many ways and can also acquire wealth through papers such as stocks or royalties.
Entrepreneurs typically have noses with broad nose wings. By contrast, professionals such as lawyers and doctors generally have narrower nose wings since their income tends to come from a single source.
As a rule however, if a person has narrow nose wing, their capacity to earn from any means other than what they are skilled at doing is minimal, whereas a person with broad nose wings will be able to make money from many sources and means.
