In the quote from Tennessee Williams' "Royal Road," he reflects on the concept of departure and the inherent human experience of transition, emphasizing that leaving can be a necessary step even without a clear destination. This notion suggests that the act of moving on or stepping away holds its own significance, regardless of where one might end up.

Williams implies that sometimes change is essential for personal growth or to escape unfulfilling situations. The idea of embarking on a journey, even when the path ahead is uncertain, resonates with the universal theme of searching for meaning or new opportunities in life.
