Nothing was wasted if you learned and grew from the experience as cheesy as it is (I guess just reiterating uniacto) but even still, your dream of writing music is not going to be determined by a degree even though of course it helps a ton in some fields, and jobs are hard to come by that will support you.
My wife has a degree from Berkeley and got passed over for a "guaranteed" job because the president (micro-managing a bit) didn't want to have to "waste" any time training. Didn't hire from within from a person with brand and company experience, hire someone who did the exact same sales job somewhere else. I say that to sort of illustrate how we can put weight on all these important things (Berkeley Degree, having it "guaranteed") and it all means crap if the person in power isn't going to hire you anyway.
This is fairly rambly, sorry. But- I wanted to make clothes, too anxious to go to college for it, started making clothes at home, actually ended up selling a lot of other similar stuff locally that me and my wife made or bought and restored (clothes, which led to books, journals, bags, etc).
Moral of the story is don't let the man tell you what you can and cannot do.
