In Defense to My Career Path

I know the career path that i'm doing in regards to my future occupation is right. My career path that i will take is to hopefully take general courses at a college, and end up making the important decision of which job i want when the time comes. I'd rather get some work done, instead of waiting to make up my mind about which career I want to do. My sister took some general courses at her college for an art major, but she later started a family and ended up choosing photography. As a result of her taking general courses instead of just majoring for an artist or something, she was able to have many branches of other jobs available for her.
