When I was really little, I wanted to be a ballerina for some reason. XD I gave up on that in about fourth grade. Then after that, I wanted to be a marine biologist, but that vanished during high school.
However, the one dream I've always had since I was very, very young is to write a novel, and I definitely still believe in that. I will get a published book some day. I actually wrote stories before I knew how to write; I just scribbled on the page and then pretended to read it to my parents. And I still have several cute little "books" lying around comprised of stapled pieces of paper with my handwritten tales on them, with grammar and spelling errors galore. Fortunately, I just finished National Novel Writing Month this November with 50,000 words, so I'm certainly on my way to achieving my goal. The closest I ever came was The Tale of Sierra WinterBreeze, a 120,000+ word story I completed a few years ago, but that was a fanfiction... though it was surprisingly popular in the Wizard101 community, haha.
