Choosing a career is an involved process that takes a lot of time. You know you want to work with animals, but might not be sure which direction to follow. The best way to choose a career is to do a lot of research. Start by talking to a career counselor or — even better — a working professional. Shadow someone who is working in a field that interests you. You can take a part-time job or internship to get a taste of what this job is like. Talk to the professionals. Most will be happy to share their insights with you.
