College rarely prepares you for success. It prepares you to follow a manual. It prepares you to conform. It prepares you to become a gatekeeper. But it doesn't prepare you for success.
"Do what you love. You'll be better at it." -Francis Ford Coppola
I think the internship was developed to fill this discrepancy. Some administrator thought a single semester-long internship was sufficient for students to decide if they liked a line of work. Wouldn't it be better if there were 3 or 5 or 20 internships during college? Wouldn't it be better if a student had many different jobs and therefore many opportunities do learn what they like?
