Retirement is generally taken once you have "enough". I suppose you could argue that college is simply pushing back retirement -- taking some of that self enrichment time early -- but that is not a good analysis. See, when you retire, you already have obtained. When you enter university, you merely hope to. The music analogy you tried makes no sense to me. You cannot work 24/7. You are not in any reasonable sense forgoing wages you could have earned by listening to music. If you quit your job to listen to music eight hours a day for four years, I would argue that you are either a fool or very wealthy, and I don't think I'd find many to disagree with me.
