You summed up the purpose of budget very nicely. I am often asked why I chose healthcare finance, it is a very challenging profession with lots of long hours. My answer is similar to yours. I have the privilege of helping thousands of children and women via the decisions that I make. I am certain that not all of my decisions are 100% right (as I know you have witnessed!), but I always put the patient first and do my very best to use our limited resources to do the most good. If I am not the one protecting these precious resources for the most important customers of any industry (patients who often can't do for themselves what needs to be done for them), who will?
I hope one day we will have enough resources to provide every needed aspect of healthcare to all patients, until that day however, you and I get to continue having budget fun every summer! (you know you love spending so much of your time with your wonderful finance guy!)
