In my University years I observed two groups of students.
The first group was ultra-focused on their studies. They attended all their lectures, turned in assingments on time and fraternized exclusively with smart or smarter students.
The second group paid attention to their studies. In addition, they had part-time jobs and projects working for local companies. They cared more about how their studies impacted their world and not just the academia. Sometimes, they were at the top of their class and sometimes they weren’t.
