Waking up early and going to work every day can certainly be a sign of a hardworking person, but it is not the only factor that determines a person's work ethic. There are many other ways in which a person can demonstrate their hard work, such as by consistently meeting deadlines, putting in extra effort on projects, and taking on additional responsibilities. Ultimately, what matters most is the quality of the work that a person produces and their commitment to excellence, not just the number of hours they put in.
