curiousity

i was just wondering what I need to do to become a chiropractor. i’ve been thinking about it for a couple of years now. every since I was in high school actually. what classes do I need to take? how long do I have to go to college for this? do you enjoy your profession? what exactly do you do on your work days? do you make up your own work schedule? how much do you make in a year approximately? what is the difference between a physical therapist and a chiropractor?
