It honestly doesn't matter what I WANT to be in the future as I've already actually joined the US Army very recently as a medic which I will stay as for at least four years, though I plan on staying as that longer. Only reason I joined was because of terrible financial issues with my family and I was left the option of serving for my country or living a stagnant life in poverty.
But.. let's see. I used to remember wanting to be a number of things a long time ago. I used to want to be a lawyer just because I was good at arguing, which isn't a very good reason, and even a comedian when I was in elementary school. The last thing I seriously thought about being, which, if I had the chance, I really think I would become, was a High School English teacher. I have many, many ideas for that subject, I love writing and would love to teach people that subject, especially considering all the methods I have in mind for improving the ways my students would learn English.
