Future plans for me? Maybe?

So I'm sitting here at work as usual, fresh out of college and thinking about how I'm giong to do on for the rest of my life. I said after I grauated, that I would never go back to school again. Well... now I don't know. I'm thinking, and tell me if this makes sense, to go back to school and get a teaching certificate of some sort. The teach at my old college (Columbia) in computer graphics or web design... something like what I'm donig for work right now. Every teacher I ever had there was in the field they were teaching. So it would be good considering I'm a graphics and web designer.

How long do these degrees or certifiicate course go for? I don't want to be in school for years anymore. Does anyone else do this? I would only be able to teach nights, which sucks too. But it is extra cash, and I'd only be working a couple days a week. Any input?
