Why did you choose your career / study programm?

When I was a little girl I loved animals a lot and because of that I want to study veterinary. But as I grew up, I didn't wanted to study veterinary anymore because I hated seeing animals suffering. 

When I was in high school I was very good at maths, physics and chemistry. Besides, I really like them.
Before finishing school I had the option to study civil engineering in chemistry  but I was not so convinced. Finally, I decided to study chemistry and pharmacy, because I like chemistry and its labor field. 

My experience at university has been good, but it has stressed me up. I am not sure in what I will specialize but I would like to do a little of everything.
