Continuous learning is talked about a lot nowadays, and it's not just a passing trend. It is both enriching and sometimes essential to be able to enhance one's skills in line with changes or even switch to an entirely new field. The joy of learning doesn't have to end with one's career. At the University of Vaasa, for instance, you can find 79-year-old Pentti Tikkanen attending management lectures alongside his twenty-something classmates. And Mr. Tikkanen has no intention of settling for a master's degree – he has his sights set on a dissertation and the title of doctor.
