Yeah, going to university in the hopes of learning discipline is like going to [some place not commonly associated with X] to learn [X]. [1]

If it's discipline you need, you'd be better off spending four years in the military. Perhaps you'll say that this is "discipline provided by others" rather than "self-discipline", but in practice I'm not sure there's much of a difference based on the ex-military folks I've met.

[1] Sorry, the metaphor subsystem of my brain is broken today. Insert your own metaphor here.
