Why did I choose my career

The reason why I chose my career (chemistry and pharmaceutics) and not another, it's because I love chemistry and science stuff, but when I was little, I didn't even know that this career existed, in fact when I was just a girl I wanted to be a veterinarian 'cause I like animals and by then my house was full of pets like dogs, cats, fish and birds. Then, a few years latter, when I was 14-15, I was really into  humanist careers like psychology and  law, I really didn't know why, maybe was the prestige, maybe was that I had a humanist side by that time, I don't know.
When I was in high school, I decided study medicine. I was with this idea for 3 years, but when the last year came, I realized that it really wasn't my career 'cause I couldn't handle the feeling of blame if one of the patients died or if I gave a bad prescription, but I still like the health area, so I had to find one career that was in the health area but not handle directly patients, so there was chemestry and pharmaceutics, I always have it in second option, so there always in my mind, but I didn't take it for first option until 4 grade of high school.
My experience until now has been very good, I'm not stressed at all and I'm really enjoying the career. In the future I would like to work in a laboratory.
