I quit my job a few month ago so I could get stuck into making some music in the way that I felt I needed to.
Dont get me wrong there is no way that I am thinking that im going to make any money out of it it was just a fact that between my other half,music and my job somthing had to give as none were getting my energy and focus the way that i wanted them to so I got rid of the thing that was least important too me(the job and good money)
Its only for about a year.
Im happy and managing moneywise plus I have a very understanding girlfriend.

As for making other forms of music for a way of paying the bills, to me thats the perfect dream.
Be it computer games, tv, film, whatever, You can still be innovative in the way you do it you dont have to "sell out" you can still do these things your way.
