be or not to be

Be a veterinary always have been in my plan, but it's not the unique thing I have been thinking to be. Specially before and after to left the school, I thought in others career options like agronomy, arquitecture(mother's frustrated dream), astronomy and be a ballet dancer. The last idea is the tipical impossible idea you have that is not bad to have, just like a dream.
So, from PSU results, fortunately, I can't enter to arquitecture, so I decided enter to veterinary medicine finally. Although I'm not completely sure of this decision, I like and enjoy some areas of what we are studing until now, like ecology and histology. About work, I would like to do something based on educate people to have other animal vision, like have a better convivence with them.
