Job offer, but do I want it?

The original position that I was offered by the company I've been talking with didn't work out. This school thought that I was too young. They said that they wanted someone that was at least 25. Whatever, that's not a big difference. But the whole thing was starting to frustrate me. The company (I wont name it, since it would be really easy for it to be picked up in Google) said that they'd call me back soon with another position. Late last week, I didn't much care if they did or not, since I was frustrated with them. I whipped off a bunch of applications to some other companies that were advertising, and got a few bites, but today, the company (which will not be named) called me back with another offer. I don't have the details yet, except that it's at a private high school teaching 10th and 11th graders, with a total of 18 teaching hours a week. (That's full time)

But now I'm not sure if I want it. I had given up on my project to find a real job a few months ago because I couldn't find anything that I thought I could do. Everything I saw was a mid career position and/or required almost native level Japanese. But last night I talked to Ai's mom for a while about real jobs, and she's convinced me that there are plenty of jobs out there that require little more than me being young, capable of learning, and being a good english speaker. So I was looking forward to having a lot of time this month to look for a real job, but with the call today, I'm being forced to make the decision between a pretty good job now, but with little or no future, or starving for a bit while I look for a real job.
