"College aged" is something of a misnomer anyway. The last college class I took, I was in my 40s. The class had students ranging in age from early 20s to late 60s, and for all I know, the one guy might even have been older than his 60s.
And what did I learn in that college class for advanced fiction writing? That the only fiction worth writing is Literary Fiction, and that if we were going to write Genre Fiction, we were to be despised. The bias from the instructor was so bad, that I made a t-shirt to wear to class that said, "Please don't tell my Mom that I write Genre Fiction. (She thinks I do screenplays for porn movies)"
Yes, I still write Genre Fiction.

And, probably worse in the eyes of the instructor,
Christian Genre Fiction.
Anyway, there are challenges and advantages to each stage of life that we are in, even for our writing. The college years are busy, but so are the career-building years, and especially if you have a young family to take care of. There is a basic truth, though, that we have time for what we want to have time for. In fact, when writing really gets ahold of you, it's no longer a "want," it's a "need." The story begs to escape from our minds and onto the page, and we find that we just cannot leave it alone. We'll take time away from sleeping or eating to write. We'll sneak in writing time on breaks or lunch. When we're not writing, aspects of the story are being worked over and over in our minds (NO! I'm not DAYDREAMING! I'm working on MY STORY!). Our characters quit being imaginary constructs in our heads, and become like real people we know and interact with, and whom just WON'T SHUT UP WHEN I NEED TO SLEEP, DOGGONE IT!
Excuse me a moment -
What's that? Oh, okay. Um, yeah. Right away. Sorry, I gotta go. My characters just told me that I need to get off Faithwriters and get back to work.
