Finish a degree in humanities and then go back or just go for computer science degree?

I'm married and I work full time. I'm a real estate agent right now and it's a great career, but I love computers. I would prefer a steady paycheck, though, because my wife and I are thinking about starting a family, so that's what is making me think about this.

If I finish the humanities degree, I have 7 classes left, but I'm starting to wonder if that's even worth it. I worry that a humanities degree is useless. At least the computer science degree gives you a skill set that you can use to get a job.

My other thought is that if I finish the humanities degree, there wouldn't be nearly as much available, career-wise, plus it probably wouldn't pay nearly as much as IT jobs.

So, I guess, my question is, should I finish the humanities degree first or should I just go for the computer science degree?
