If you take a minute to consider all the circumstances beyond your own experience, you'll soon see it's very easy to feel lost.

I confess I have absolutely no idea what you mean, but then again the concept is completely alien to me at least in the context of the direction of one's own life. As I said, this is something I've never experienced. Nor, frankly, wish to.

Nobody goes into science to make money, admittedly, especially those of us who want to join the tenure-track rat race (the point is, though, that we often end up making money anyway). I know it's a Sisyphean task. I still can't not try. It's like it's embedded within my being. I guess in your case, music is embedded within your being. Problem being, I suppose, that a biology degree has far more bill-paying avenues than a music degree, and my dreams and ambitions are in, well, biology; even if I don't get a tenure-track job, there are numerous other ways to get into being a PI of some kind, and then there's industry and government and all sorts of folks that are hiring, hiring, hiring.

I have no idea if you're still in university, but maybe - this is cliche - pop down to the career center and poke through its offerings. You might find opportunities yet.
