"Making mint" is a phrase used to describe the act of earning a lot of money, often quickly or easily. There are plenty of other phrases and euphemisms that can be used to describe the same concept, including "raking in the dough", "bringing home the bacon", or "making a killing". Other phrases may be more specific to certain industries or contexts, such as "booking big gigs" for performers or "closing lucrative deals" for businesspeople. No matter which phrase is used, the concept remains the same: successfully generating substantial income. It's important to remember that making a lot of money isn't the only measure of success, and that there are many other factors that contribute to a fulfilling life.
