Why do I want to be a vet ?

Well I like very much animals but specially cats family, when I was smaller i want to study nutritionist, biology teacher, biotechnology ,something with genetics and vet. I decide to be a vet because It was one of my options but at the same time I want to study nutritionist, now I really confused about want I really want to study.

at this time I really like college and friends college I never thought that I will found friends like me and I really enjoy my career its really funny but I have to study a lot.

 if I stay in this career I want in the future work in the zoo or with exotic animals when I was I child I always want to be like jeff corwin  in the wild and search strange animals.

Now I don’t know what to study but the only thing that I know now its that I want to study something  relevant in biology
