Tired of Being an Correctional Officer Where Else Can I go?

I am tired of Being a Correctional Officer, Its not a bad job but I like physical work moving around and stuff . I am stuck in a place for 12 hours a day and the pay in the NC area aint that good compared to other states.I was thinking about Trying VA DOC. Working 12s are hard They are not just for me, Work 12 Sleep 9 Hrs. Then my day is gone. Any Suggestions On what I should do Iam only 21 Years old. And people where I work say this is a bad place to start at my age. I would like to finish getting my degree in criminal justice but I am unable to. And We only get paid once a month.
