Why did i choose this career?

When I was a child I never had a real idea that I wanted to do in the future. I didn't see me as an actor, office worker, or something. But I became older and I had to choose, the moment that i really start to question this was in my last year of school, I know that everyday I had less time to make one of the most important choice of my life, and I decided to inform about university programs.
At the moment of applying to university my options are food engineer and pharmaceutical chemist, and finally I chose to study the first, acord to my experience in the university this is the correct decision, nothing about the career disgust me, and I more interested that when I entered.
 When I finish this program I want to work in a big food company like Nestle and Coca-Cola company, or in McDonald's to finally know if the meat is made of real meat.
