I want to be a Doctor because I think as a career it would be constantly changing due to new discoveries and treatments as well as interesting and diverse. There are so many speacialities and illnesses that one can acquire. Not only would it be satisfactory but if you love Science, not only do you get to help people and make a difference but you get to work with the subjects you enjoy in an analytical way, which I personally think is rewarding. I also think it's good because you take an active role in making a difference to someone's life. I agree with Aisha Tara, even if doctors were poorly paid I would still want to do it.
