I wish I would have tried to do it.
Her work life is set, but it still does nothing for personal growth. You usually need both to be successful. I wish I would have learned this earlier in my life. I went to a commuter school and did not get the full college experience.
You'll probably never experience military life, and probably neither will she. Does that make your life any less of an experience? No.
Finishing a degree online may not have given her the college experience you had, but that doesn't make the experiences that she did have any less meaningful or fulfilling, especially for a young teenage girl.
Well, we're all humans, and we humans have certain needs, like study, love, friends, adventure, etc, and the need to share similar life experiences with many other humans, like with everyone who also went to college.
This is why I think talk of a higher education bubble is too general. I am certain many colleges are overpriced but, by no means will colleges ever go away, or even be extremely different. We are not talking tulips here.
I hope tuition prices come way down, but the college experience is here to stay. Heck, if you're desperate for great employees who could have their pick of jobs, you tend to turn your company into "college". Just think of Google or for that matter Microsoft, or most big tech companies and their "campuses."
