I love kids, being a parent was the only "dream" I was really sure of when I was younger. But I can barely afford to support myself, and as a woman in my upper-30s I can see the door of opportunity closing rapidly.
Thankfully, not all is lost. Working in education means I get to do my part to "put better and smart people out there" without having my own kids. It still hurts that I can't have the life I wanted, but at least I have the ability to positively influence future generations.
