Where do you draw an ethical line when you live your work 24/7?

I have struggled for years to follow my calling to help children.  I believe that God demands us to take care of orphans if we can.  In 2009, my life changed forever when I said yes to a dying orphan in Ethiopia.  After bringing my daughter home, I realized that I could no longer do the work I had been doing in residential rehabilitation for substance abuse.  Five months later I was working as a case manager in therapeutic foster care.  I told my new employer at the interview that it was my intention to adopt from foster care and I was told that it was difficult but not impossible.  Nine months into my new job, my husband and I were ready to persue licensure for foster care.  That was the beginning of the end for me at the agency I worked for.  Foster care and my calling to do it was more important to me than the fact that my boss really did not want me to do it.  She saw it as a conflict of interest that I wanted to work in foster care and be a foster parent.  She regularlly reminded me of how much she hated it.  She even asked me one time that if she just gave me twin babies if I would stop fostering.  My work never suffered, but she always had a made up reason for how it effected me.  I ended up leaving that position to work at a similar, but Christian child placement agency.  My new boss did not want me fostering either but was able to give me a ligitimate reason for it and a 6 month trial to see how it would all work out.   Most of the administration in my field believe that I should not be “bringing my work home.”  It is great that I am passionate about helping children, but they cannot see beyond how my decision may impact them and the business.   I think part of the problem is that I cannot have my license where I am employed due to Colorado law.  So in essence, I am always working for the competition.  I see it as just another skilled foster parent willing and able to help those in need.  This is where my moral compass points to.  This is where my faith is leading me.  My clients love that I have been where they are and that I understand on a personal level what it means to parent children with challenges and deal with a system that is so very flawed.  I still cannot tell if my blindness to help children in need is in direct conflict with what I have chosen to do professionally.  It seems to me that it is good to “practice what you preach” as certainly Jesus did; however, when so many people in my field are against it maybe I
