Money and Birth

I have a very strange relationship with money and it is time to work on changing it.  My work has always been something that I was passionate about (except for that short stint at the bakery, shudder, working for pennies and getting up at the crack of dawn to walk two miles to work).  So if you are driven to work for the love of what you do, what you are paid, as long as you are able to eat and keep a roof over your head, seems strangely nonessential.  I have attended 10 births and have only once received somewhere close to a doula's fee.  But there is nothing like the miracle of a crowning baby, even thinking about it the power of that moment floods through me, and witnessing this moment, and the things I learn about myself and about birth with each mom and labor seem payment enough.  And after a birth I walk about on a natural high larger then anything I ever felt in my "finding myself days."   The sun reaches me through the car window with an unusual brilliance.  In my sleep deprived haze, mundane tasks are exhiliarating... 
But my friends and husband gently suggest that if I charged for my services or charged more for my services, we could afford that Mazda 5 and retire our beat-up Golf that barely fits our two carseats, we could maybe take a vacation that isn't a trip to see family, we could pay down some of our debt, and those things sound pretty attractive.  So I am trying very hard to attach more monetary value to my services.  This isn't easy.  Maybe one day I will have to take a course from The Birthing Business Institute.
But how did I start this strange relationship with money?  Sometimes I wonder if credit cards aren't also part of the problem.  Too often I pull out a bright little shiny plastic card, and whether I can afford it or not, the clerk says thank you, handing me the tiny little slip to sign, a slip that is shredded when my wallet reaches its maximum capacity of credit card slips.  Or maybe it was the super-abundance of love that I was brought up with, a commodity  you can't pay for and which is what really drives me.   And love is present at birth in rare form...  But I will work on this, I will!
