Anyone who goes to university with no clear plan for learning a particular subject to a high degree of mastery, a subject that points clearly to a particular profession or well-defined trade, is making a mistake.
Anyone going with the idea of "having fun" in college is likewise probably making a mistake.
Unless a high school senior approaches college like a job, with expectations of work every night and on weekends, with maybe a night off a week, is making a mistake to go to college.
I saw so many lazy, spoiled kids with silly majors, take so much retirement money from their poor parents, only to piss it away by partying for a year then flunking out... interfering with serious kids' attempts to work and progress in school. It was infuriating to watch.
The lazy, spoiled kids should get a room off campus, no tuition, no fees for books, etc. then party without wasting their parents retirement savings.
