One can find a lot of advantages to being a doctor; however, one will also have to be aware of the sacrifices that come along.
There are a lot of reasons why I want to become a doctor. I am interested in the field of study of becoming a cardiologist.

I find the study very interesting.
More towards that, there are a lot of old people in my area that I wish to help.
Due to financial issues and problems, these old patients are unable to go to the hospital to get them treated. Looking at all these problems, my desire to become a doctor grows even more.

I have always been inspired by the work of doctors and have high respect for them.
I am in awe of the level of concentration, hard work, dedication, and sincerity put into the work.
I want to become a doctor because there is nothing more satisfying than helping a person in need.
