Why did i choose this career?

Well, i really dont know, during my whole life i wanted to study medicine, that was the only career i knew, i think because my parents are doctors. But when i was is high school, i feel that was not what i liked. I started thinking about study art or something like that. I also liked engineering, but i didn´t want to dedicate my life to that, so i really didn't know what to study.
When i finished highschool, i decided to study medicine, because i had no other option jaja
I enter in a program of studies for pass to medicine, but that really doesn't liked me. In that program, the University showed me other careers....
