Even though college ended up not being the romanticized experience that she expected, why is Helen still glad she went?

From the text:

But I soon discovered that college was not quite the romantic lyceum I had imagined. Many of the dreams that had delighted my young inexperience became beautifully less and "faded into the light of common day." Gradually I began to find that there were disadvantages in going to college.

The one I felt and still feel most is lack of time. I used to have time to think, to reflect, my mind and I. We would sit together of an evening and listen to the inner melodies of the spirit, which one hears only in leisure moments when the words of some loved poet touch a deep, sweet chord in the soul that until then had been silent. But in college there is no time to commune with one's thoughts. One goes to college to learn, it seems, not to think. When one enters the portals of learning, one leaves the dearest pleasures—solitude, books and imagination—outside with the whispering pines. I suppose I ought to find some comfort in the thought that I am laying up treasures for future enjoyment, but I am improvident enough to prefer present joy to hoarding riches against a rainy day.
