Best job that allows for college and affording to live on your own?

So, I know this sounds like a high schooler's question, but there's some backstory. I am 21, and after being screwed out of college three separate times, I am determined to get re-enrolled for classes this August and finally complete my degree over the next two years.

Thing is, my parents are moving across the country so I need to be able to afford to live on my own. I need to make AT LEAST $1600 a month.

I keep telling my boyfriend that serving is my only option. It's flexible, is get tips and could pick up an extra random shift if I were ever short on money. He insists that there is too much drama in restaurants and that it will hurt our relationship.

So, to at least humor him, I'd like to hear what everyone says the best job for someone enrolling back in school, who also needs to afford living on their own would be. If you think it is serving, please say serving. If you have other suggestions, I would love to hear ideas. Thanks!
