Dreams of being a prima ballerina were quickly dashed. It's one thing to parade around in a leotard at ten and something ENTIRELY different to do so at age 20 in a room full of my peers. Needless to say, after the class was over, I shelved that dream. But it was okay. If I hadn't tried it again, I might have always wondered.
Some dreams may not end up being the right fit for you, like ballet for me, but at least you tried and won't always wonder. Other dreams, though, might just surprise you, if given a chance.
What dreams have you pursued in adulthood? What things did you do as a kid that you wouldn't dare do as an adult? Have you watched The X Factor? If so, who are you rooting for?
