The “highest good” of a human being according to Aristotle

Chris is pursuing his dream of pioneering the research and production of affordable medicine. In his spare time, he is honing his talents as a cellist, engaging in philanthropy, and maintaining an active life in the politics and culture of Winterfell’s Point. Dan is enjoying the six-figure salary of an adjunct professor. In his considerable free time, he hosts renowned parties at his mansion and travels the world during the academic winter & summer breaks. Emmett devotes his life to his family, his church, his studies, and his job. He never says no when his sister asks him for a ride or a coworker asks him to cover a shift. When not in class, studying, or working, he is usually stocking and manning his church’s food bank as well as the Winterfell’s Point shelter. Who is fulfilling the “highest good” of a human being according to Aristotle? Why not the other two?
