Why did I choose my major?

As a child i wanted to be a ballet dancer, but we did not have enough money, after that i wanted to had a chocolate factory, like in the movie, and eat chocolate all day, but i think that’s not possible either. In high school, i used to read a lot, so i wanted to have a library, also i started going to private painting classes, where i fell for art. When i finished high school i had no idea what i wanted to study, and my score on PSU was useless, so i entered the pre university. After that year, my score was better but not enough for study arts in University of Chile, so i apply for Etapa Básica in the same university and i was accepted. So far things have been not that bad I think, now i just want to finish the career, work enough to leave my house and go to travel anywhere.
