I've always looked younger than I really am. I've often acted half my age as well. Somehow, though, I feel that I've missed out on a lot of the madness of childhood while I was growing up. Things are rarely the way we imagine them to be and we keep holding on for a dream until long after we've woken up.
I've also always been fascinated by the energy of youth, by people who live with passion rather than just live. I have constantly seen children younger than me who had more talent or knowledge than I did at their age or even when I was older.
