Degrees and advice

Hello,

I would like to ask you wonderful people for advice. I am at that stage where I am trying to figure out what I am doing with my life.

If I could make it to my dream career I would be living in Geneva, Switzerland and working as a healthcare system consultant for the W.H.O. I don't even know if anything like that exists, but that's what I want to do. I want to help develop a global healthcare system so that everyone has decent healthcare available to them.

Right now I have a Bachelor of Science in Global Health from the University of Washington and I'm planning the next phase. I am thinking that the next step is an MPH program (Masters in Public Health) with an emphasis in health systems and policy. I'm also considering an MPH/JD (Juris Doctorate) joint program. I think that I definitely want to do the the MPH and the JD, but until the last couple of weeks I've always wanted to go to Medical School. Since I want to get into health systems and policy I still think that the MD would be a good degree to have. But is this way too much, or am I just covering my bases? An MPH (hopefully a 1 year program or a joint MPH/JD), the JD, and an MD (possible without the residency, since I'm not sure yet if I want to be a practicing physician). This plan would be anywhere from 8 to 13 more years of schooling (during which I hope to still work at least a little- I need to make a living).

Is it too much? Is it covering my bases? I want to be the best in my field I want to go through all of the programs so that I know what I'm doing and can do it well. What do you think?
