Hard-working describes someone who keeps pushing through tasks even after the excitement wears off. People high in this trait may finish what they start, stay with boring or difficult work, and keep going even when they are tired, distracted, or no longer enjoying the process. They often treat persistence as a responsibility, not just a mood.

At its best, this trait can show up as discipline, dependability, follow-through, and the ability to build real skill over time. At its extreme, it can become overwork, difficulty resting, or judging themselves too harshly when they are not constantly productive.

A recognizable fictional example is Rocky Balboa from Rocky. He represents someone who keeps training, enduring, and showing up even when the work is painful, repetitive, and far from glamorous.
