Why did you choose your career?

When I was a child I thought of becoming a doctor, because I found that very beautifull work, and I admired their ability to heal people , but when I grow up and meet another professions, I learned about scientists, beings capable of discovering new things that can help us to live better and taking care of our planet, so I decide to becoming in a scientist. But there are many kinds of scientists that studys different areas, and in high school I dedicated to investigate about it. I felt a strong interest in astronomy, but I realized that this did not help much in the progress of solutions to current problems, so I decided that could be a hobby and not what I would really study. I also realized that I wanted a career that would give me the freedom to work in the area that interested me when it interested me, that's why I choose biochemistry. And my experience until now at university has been good, I like that every day I learn something new and I am always getting to know people who have the same goal as mine, to build a better world.
