Four years to "find yourself", get drunk, and generally waste time? That's what the majority of people do (in the US at least).

The majority of my undergraduate classes amounted to:

* practicing reading * practicing writing * practicing participating in group discussions * practicing demonstrating concepts (maths and proofs) * practicing a second language

For most of those courses, I could have been handed a syllabus of topics to learn on my own, and then taken a final exam- I'd already had plenty of practice writing and speaking at that point outside of school, so everything but the second language requirement for my degree could have boiled down to a few weeks or months.
