I've been listening to Dr. Michael Sugrue's lectures on Plato, Socrates, and the Dialogues, and many of these words tend to come up often. I like his descriptions best. His one on arete would challenge this definition of "excellence of any kind" to be one of a specific kind. He uses an example of a horse trainer striving towards arete to become the best moral "techne"(technician) based on the knowledge they continuously seek.
Specifically:
To make a distinction between technē and arete, the value of technē is the end product while arete values choosing the action that promotes the best moral good.
