Why I´m Studying Odontology?

When I was in 10th or 11th grade of the school I release that I want to be a Dentist. After, I was very undecided, in the school I was in an artistic elective where I discard to study design or architecture, my other options. I like very much to do things with my hands, like crafts or draws, but I am very bad to get new and good ideas, also I like very much the science, human body and help people, so I decide to study odontology. Now, I'm not happy at all with my decision because the academic charge is too big, and It's a career too difficult and stressful, this demotivates me a bit, anyway I know that I will be an excellent dentist and a happy person. I weren't certain about my decision until I postulate to this career because I'm very hesitant but finally I made the decision.

What about you? Your first option was this career or other?
