Can I live on this salary?

As someone who is looking at careers before I enter college in about a year and a half, I've been wondering about what sort of salary a single person can live on reasonably. Now, I could go into almost anything I wanted to and make tons of money (I'm lined up to be valodictorian of a large school) I want to do something that interests me. And I don't really want to go to school for a lot of years. I'd prefer a bachelor's degree, and would be willing to get a master's if it was necessary for the field I wanted to go into.

I love animals and lately have been looking at being a veterinary technologist (which is a bachelor's, not an associate degree). However, the mean salary is only about $30,000. Is this a reasonable salary for a single person - would I be able to save up for cars, maybe eventually a small house, etc, as well as cover essential costs of living? If not, are there other options I should look at for getting into veterinary medicine without going to school for many years to become a doctor? Any suggestions and thoughts are appreciated!
