In my work with young musicians in particular, I have noticed some categories of beliefs that stop musicians from building careers in music.  I'd love some feedback from folks that have build a career of some sort in the music industry of other insights that help up coming musicians.  

I'm currently a recording arts major in college and am in need of a certified engineer's assistance answering some interview questions for a career research paper. The major problem is that i'm running out of time to write the paper fast and i'm getting a lot of yes I will do the interview and then no response..

I know that we all are trying to do the same thing, but in my case a large part of the problem is focus. What should I do if my interests range from wanting to sing Broadway to songwriting to becoming a session/background vocalist - whatever it takes to be heard?
