Why do you want to be a veterinarian?

When I was a child I wanted to be a truck driver or a fireman, an architect, an artist, a graphic designer or a publicist, later I take responsability with my aspirations and I decided take the PSU and choose a career related with sciences. Until the last step of the secondary school my ways was that of an incipient humanist in fact I expected study some career like that I mentioned, was not so, I would be a biological and chemical sciences teacher! however when I heard about the program of the veterinary medicine I fall in love haha... I always said ''well, I can be a teacher in both careers'' and therefore I wanna be a Veterinarian and a Sciences Teacher.
Until now my experience at the university was a little hard but I perceive a sosteined progress on my study, must first gain the experience.
I would work with another persons who want to share and develop the knowledge, and influence upon another younger minds, maybe this place can be a school or a laboratory.
