Need help with my career choice?

Ok. So I'm twenty four years old I graduated from one of those vocational school with an as degree in air conditioning. its been about a year or so now with no luck finding a steady job. I was employed with a local contractor who hired me for about five months or so. it didn't really worked out that's why he had to let me go. I wasn't picking it up very quickly. I honestly don't really care for school I always had a hard time focusing on any subject. I was thinking about going back to school so I can either pick a different career or pick something that can benefit me in the long run what I spent thousands of dollars on. this school year I end up becoming a after school leader for the youth. I defiantly enjoyed it. I love working with the youth. but I don't know if I can do it for years.

what you guys think I should do? this economy sucks :(
