<human>: *Throwaway just to dissociate my normal name from a candid conversation about employment....*

So.  Here's my dilemma:  I graduated college in May with a degree in music education, and I hold a certificate to teach grades K-12 in Pennsylvania.  I tried pretty hard to find a teaching job for this fall, but it didn't happen.  School districts are looking for teachers with experience, and especially in music I find that when a teacher leaves they usually have a 'strong suggestion' for who should fill their place.  This past July, however, I landed a job as a full time audiovisual technician for a company in my area.  (I worked in the a/v department for my college for all four years, and am super grateful that the experience landed me a full time job and a part time job on top of that!)  So since July, I've been working a day job in a corporate environment--the exact kind of environment that made me want to teach instead anyway.  I've been living at home and saving money like crazy (I'm one of those graduates with an obnoxiously large debt in student loans).  I would much rather be teaching, but to do that I'm going to have to start out subbing day to day to get the experience I need.  What sucks is that my full time job pays better than subbing (which is inconsistent), and once the school year ends in June I won't have a full time gig to go back to.  Any ideas?

Can you give me the gist of the text in a nutshell?
<bot>: In this economy, is it responsible to quit my full time job to substitute teach, knowing full well that it will lead to a very uncertain spring and summer, and possibly beyond?
