strive

This word conveys a sense of persistent, arduous effort and determination. It suggests a long-term commitment to a goal rather than a brief attempt, often implying that the objective is difficult to reach or requires significant personal growth.

While it can describe a positive pursuit of excellence, it also carries a connotation of struggle or conflict when used in the context of opposing forces. It differs from "try" by emphasizing the intensity and duration of the effort involved.
