Why did a choose to study veterinary medicine

Well since i was a child my dream always has been the veterinary medicine, i have been always involved with the animals. My grandfather used tu have cows and pigs when i was a child and i remember that everyday i used to wake up early in the morning so i could go with him to get the milk from de cows. For a long time when i was growing up i decide that beeng a veterinary surgeon it was like some kind of fantasy and that a wouldn´t make it or that it was a bad choice of career, but when i was in the last year of  high school i decided that it was the only career that would make me happy, it was all that i liked and that was what made me choose it. I had another choice that i liked, i thought about endocrinology medicine, but thinking about it, i realize that it wasn´t the best for me. The experience until now has been really good i think, i don´t really like the vision of the univerity about the career, but i thought that i would do what i liked at any university, that is the fauna conservation, and doing more than that like showing to other what it means that, and how important is that all of us should be more conscious about it, that the animal are more than "things" and that all of us should care more about them.
