I think success is normally used in reference to other people. But true success, that fulfills, is defined based off of each person. The goals they set, and how much of them they achieve.
I assume you meant success of personal growth. Because if you means success in any context, then it's just the achieving of some measure. For example, a snail is successful after it crawls an inch.
It's rather something subjective. So my definition is knowledge of the universe.
