What do you think of my plans?

I am 18 years old right now. I want to start Respiratory Therapy school in the Fall. Once finishing that I would like to study Theology online while working as a Respiratory Therapist and continue to live at home for another year while I save as much as I can and then put a down payment on a house by the time I'm 23-24. And after I finish my Theology degree, I'd like to work in the medical field and be a pastor eventually. And then I can have medical experience for mission trips to help people with medical problems. What do you think?
