As Aristotle wrote, all virtues can become vices when taken to their extreme. On one end lies what Aristotle called vulgarity—excessive spending beyond what circumstances warrant, often to make a show. It’s common among chasers. Equally damning for Aristotle was the other extreme—a focus solely on doing things more cheaply and amassing wealth rather than using that wealth for a higher purpose. It is this vice that leads to a major injury from overstretching: becoming a cheapskate.
