Why do you want to be a vet?

in my childhood (6-8 years) I desire be a veterinarian, later i change my opinion and in this moment i prefer informatic engineering, because i like machine and tecnology instrument.
when i postulate i put
-Veterinari medicine.
-Agronomy enginneering.
-informatic engineering.
 I dind´t change much XD.
Finally i choose Vererinari medicine because i like work with animals. and i prefer work with free animals or farm animals because i don´t like work locked into the 4 walls.
