That's definitely a better answer than just citing a career. However, as I dig into in the essay, when we aim for a state of mind or feeling (like "happy"), we tend to miss the mark. I think that's why Aristotle didn't define the aim in life by "happiness" or some state of mind like that. His contemporaries were already doing that, and he didn't see it as correct.

I think beyond the career aspect, we need to look at the goal of life as less to do with a feeling, and more to do with a certain kind of activity. I think that's an important point. And when one is engaged in that activity, they'll very likely be able to pause and identify that they are, on the whole, happy. But they weren't aiming for happiness. And I think that's the point.
