Back to work??

When my son was born I ended up staying home with him. This was never my plan but once he was born I just wanted to be with him all the time, so I followed my heart and stopped working. I had three more kids and now my youngest is going to kindergarten next fall. I have worried, brainstormed, and thought about what kind of job I would start doing when he went back to school, assuming I would figure everything out by that time. Well it’s almost here and I still have no clue! I know tons of things that I don’t want to do, I need a flexible job and working from home would be awesome, but when it comes to working toward a certain career or job, I’m clueless. Do you have advice of figuring out how to choose or find the right job for you? I’m ready to work, and want to feel productive but don’t know what passions I have and how to pick a job. Please help!
