I think we understand how the human brain develops now a bit better than we did 50 years ago. And that at 19 you're basically not fully cooked yet. So yeah, at one point you were thought to be fully developed by 19 and that meant you should go get a job and put an oven in the kitchen for the little lady. But now we know that your attitudes and opinions will (or at least are likely to) change a great deal between 19 and 25. This also means your motivations and what makes you happy will change. But if you're concerned with locking down the 9-5 as soon as possible, then you're much less likely to find something that actually makes you happy.
