V ictory can stop you from moving forward just as surely as defeat. Accomplishment is often viewed as a final destination.
Success is a state of being rather than a target.
Certainly you want to move toward specific goals and achieve them. The real value of success, however, comes in the process just as much as in the result. Living successfully means that each achievement is the starting point for another achievement, rather than a place to stop. It's natural to feel satisfied when a goal has been achieved. Just make sure that satisfaction doesn't get the best of you.
