FOR VETERINARIANS ONLY?

I just finished high school and am planning to become a Veterinarian. How do I go about this? Will you tell me the process you had to take to become a Vet and if it has benefited you? I am planning on opening a Dog Shelter and want to become a Vet for financial issues and to start the business and to also take care of the animals instead of hiring a Veterinarian. Please, some assistance would be appreciated.
