“Dedication”
Dedication is the act of being fully devoted to something, whether this is something intangible, such as a task, goal, or desired outcome, or something that you can feel yourself physically being a part of, such as such as a cause, religion, sports teams, or another person.
It is one of the most powerful forces we possess with which to shape our lives and realize our goals. It is a positive character trait, and a trait that is most likely to lead to your success in life.
