Why did you choose the career for which you are preparing?

The career for which I am preparing for is a cardiologist. Ever since I was a little girl my mom has told me that I always said that I wanted to become a doctor when I grew up. I was never really sure of what kind of doctor I wanted to become until my sophomore year in high school. I had to do a science fair project for my biology class so I decided to do something on the human heart. While doing the project, I found out that my family has really bad health history with our hearts. I also found out that my grandpa has had 9 heart attacks, that the doctors know of, and is still active and alive. After I found that, I knew I wanted to become a cardiologist. My mom asks me from time to time if I still want to become one and I tell her yes. I have doubted myself sometimes but it'll be worth it in the end.
