skeptic

So I graduated high school two years ago, but struggled with college and left after one semester. Got a job doing office work, liked it a lot, but there was no room for advancement without a college degree, so I decided to go back to school full time. I've been back in school for about 8 months now, and I'm really struggling, I'm lazy and have no motivation to do any work. I live on my own and have been living off savings the last few months, but the money is slowly running out and I decided to start looking for a job a few weeks ago. I like working a lot more than going to school, but I'm aware how important a degree is, so my plan is to work full time and take maybe 1 or 2 classes at night (yes, I know it'll be very hard, but taking school slowly should make it a lot more manageable for me). The problem is, I can't get a reasonable job. I've been applying for a lot of administrative assistant type jobs on craiglist, but haven't had any luck, and now I'm thinking of joining the military. I did some research online, and spoke to a recruiter last week, and it looks like the army might be a decent option. I know it won't be easy, but at least they'll give me some free training in a field I'm interested in, help pay for college, and basically offer me a job when no one else is willing. Any advice?
