Working Angst

I'm thinking about going back to work.  As in a job, outside of the house, making money, etc...

The problem is I don't know how to go back to work.  I've had two (paying) jobs in my life and I can't say that either were life affirming or even these days would pay the bills.

My first job was as a cashier at Publix. And while I enjoyed that job because it wasn't demanding and I could take vacation whenever I wanted, it doesn't really pay a lot of money.  I can't imagine how I would support two (soon to be three kids) on minimum wage. I worked at Publix for 7 years and became office staff which meant that I counted money and tried to make sure that none of disappeared.  Even if I went back at that level, I still wouldn't make enough money to live on. 

My second job was teaching high school in Clayton County public schools.  I loved parts of that job.I loved working with (most) high school students. I loved the subject matter.  I loved the vacation schedule.  However, these days with cut backs and other things, I don't know if I can teach again.  And that is the only thing I know how to "do".  And yes, it would pay the bills and while there wouldn't be much money until the youngest went to school himself, it would be enough to eat ramen and peanut butter several times a month.

I've also been out of the work force for the past 4 years.  Some of it by choice, some of it by the recession and schools not hiring teachers.  So yeah, even if I had a "in demand" skill, I don't know how to go back to work. 

I suppose I should seek some kind of advice?
