there's an awesome book by sunita puri md: that good night. it's about her experience becoming a palliative care doctor (hospice). it's a great book!!! also you can see her interview with zdogg md on you tube. they are both amazing.
in arizona the job of nurse practitioner is identical of that to a doctor. so you would be doing all the things sunita does. the only difference is you won't make as much money as a doctor (but you will still make great money!) but NP's have more time off and more flexibility.
get a job working as a medical assistant in a hospice after high school and you will see first hand what np's do all day and get lots of first hand experience with patients in that setting.
