What part in animal health care should I be in?

I woke up thinking what part should I be in. I mean there are so many wonderful choices. Like a horse, cat, dog, bird, or fish technician. Or should I be a normal vet. Maybe working with livestock. What about exotics. I already know about everything in these careers, I just know that I can't do every one of them. I'm not gonna choose my career based on your answer, just reference. C'mon and help before my brain explodes :P
