I was once obsessed with math that I thought math would be my future career. As I went to high school however I found out that I was not interested in math itself but was only interested in solving math problems on the test. I then wandered taking various classes to find what I was interested in. Biology class that I took during the wandering brought me to totally different position. Biology was a subject that has a lot of things to memorize but I enjoyed it. And unlike math I could feel that I was interested in biology it self. Also I always wanted to have a career that I could feel my work is being used valuably. Since doctor is a job that aligns with both my interest and orientation at the same time, I thought it would be an optimal job for me. I'm not sure yet whether this is my suitable way, but I think I would make a same decision even if I go back to high school.
