I'm a nursing student, but also want to become a CPA?

I have finished year 1 of nursing and I am an LPN. I have 3 more years to finish my Bachelors of Science in Nursing. Here's the thing..I'm taking tax prep courses on the side and I love it. My REAL pion is Nursing. I love the patient aspect..but the abuse, coworkers, and extreme stress have made me think twice about committing to it for an entire lifetime. I don't want to be miserable and on anti-depressants or anti-anxiety medicines like every other nurse. I LOVE numbers, on the other hand, and find taxes to be quite interesting. I'm organized and pretty good at math, if I can say so myself. My ultimate goal was to have my own tax office and be my own boss..but I know this is going to take a couple of seasons of experience, building clientele, etc. I am doing it part-time, on the side, as I work as a caregiver and finish my Bachelors of Science in Nursing..however...if I want to become a CPA...is this even possible? I don't want to have to wait 10 years to get to my goal...trying to see how to sort out this 5-year plan, for myself, with something realistic. I *do* realize that it MAY be 10 years before I'm really banking some money..but I want to have everything set and in the works. I want to define my path in life..and taxes are MUCH more stable than nursing. I would love to do nursing for the love of it..on the side..during off-season for taxes.
