Doctor or Nurse Practitioner Specialty??

Ok, I've decided that I want to become either a nurse practitioner or an osteopathic doctor. I want to work with EVERYBODY (adults, children, etc.). However, I have been thinking that instead of going through 8 years of schooling and a 3 year residency in family medicine, why not just become a family nurse practitioner? Right? However, Im wondering what the most versitile patient involved medical specialty that there is.
what do u think? FNP, or a medical specialty (please specify)
seriously, both make great money, and Im fine with which one doesnt make as much.

thanks, y'all!

I would think that if money is not an issue between the two fields, how about going for the career that has a more affordable education as you mentioned, the (family) nurse practitioner

For general career info: http://www.bls.gov/oco and can search 'registered nurses' (NP is under RN), 'physicians' or such.
