When a person learns to be frugal or careful with spending, they become creative in finding solutions to problems.
Here is one perspective on how being thrifty or frugal can lead to innovations, similar to how other limitations can foster intelligence:
Necessity is the Mother of Invention: - When resources are limited, it compels people to think in unique ways and find new solutions to problems or tasks. This kind of limitation can lead to innovations that might not have existed without these constraints.
For example: In 2020, due to the intense demand and shortage of cleaning supplies and sanitizer in the market during the pandemic, many people and businesses thought of alternative ways to create their own sanitizer.
For instance, some businesses used isopropyl alcohol and aloe vera gel to make their own hand sanitizer that could be distributed to their employees and customers. Others used rubbing alcohol, glycerin, and fragrance to formulate their own sanitizer.
