I'm 30 and I STILL don't know what I want to be when I grow up!

I have spent the weekend researching various careers, but I can't settle on just one! Perhaps
I'm destined to be a perpetual student. I'm stuck between historian and registered nurse. I'm supposed to narrow the field down so that I can do a project for my technical writing class in college. Seeing as I'm there to complete the ADN program, maybe I should explore my (for now) chosen field more in depth. Fine, that settles it! When I grow up, I will (maybe ) be an Obstetrical nurse! Wish me luck and if you are an OB nurse, let me know how life is treating you!
