Success is a journey not a destination!

One must first define "success" in order for this statement to have any meaning, as that word is very subjective.

Success in a real, simple meaning with one variance your standard of success.

A pregnant woman might define "success" as having given birth to a healthy child; therefore, those nine months of the journey are not necessarily "success" for her, but the journey toward a desired outcome, her "success". In that sense, it could be a destination. Perhaps in retrospect, those nine months could be perceived as success depending on the outcome.
