A simple principle applies to earning higher income. The more you know, the more money you will make. This principle has been valid for thousands of generations and is still true today. You will actually make more money the further you learn. This is especially true in finance. If you have a Master's in financial management, for example, you will be able to earn more than someone who has a degree from aerospace engineering.
The more you learn, the more you earn
A famous rock star once said, "the more you learn, the more you earn." In business, knowledge is key to success. The same applies to business. The more you know about a specific field, your earnings will be higher. Hence, it is important to remain in school and further your education.
