Where has the time gone?

I am almost 25 years old and I don't think I have done anything with my life. What I am trying to say I dropped out of school and got pregnant. Don't get me wrong I love being a mom. But what would of happened if I waited to have a kid? What I mean is I had a plan. I would finish high school then I would of went to college then find a good job, then get married and have kids. I would of done it in that order. But things change. I would like to finish school someday.
