What do I want to be?

I have not figured that out yet. I have had many ideas but none of them have ever come to fruition. I just want to do something that I enjoy. So for now I stay at home and take came of my family.
I am a few units away from completing my BS in Kinesiology but now I don't know what I would do with my degree. I took a certification course to become a doula but after my most recent birth I am not sure that I would be able to help a woman during one of the most painful (yet rewarding) times in her life. I once thought I could be a personal trainer, but I think I would need to be fit first. Now I am thinking I would like to take up photography. I think it will have to start as a hobby, as I should concentrate on my girls and school (at least until I graduate). But maybe if I become good enough someday people will pay me.
