goodbye childhood

So in a matter of hours i will soon turn 21. In our culture today 21 is a big birthday to celebrate because that's the last milestone you look forward to. From here on out that is it I am an adult. There is no more just "oh she's young she still has time to learn" but rather this is the time that i need to be learning and figuring these things out. Yea I cold probably get away with still having a child's heart, but that's it. It is such a weird concept to fully grasp. I am now becoming an adult. My life is changing and reality is starting to hit. The things I always imagined that I would some day get to are soon to be the days that I am going to need to start getting around to them. I never thought that I would be the kind of person to freak out as I aged, but here I am so blown away by this concept of growing older. With age comes wisdom and wisdom is something that I am so desperately seeking, but i guess I just always saw everyone else getting older as I stayed the same. Almost as if there was no sense in aging for myself that it was just the world around me. Now I am realizing that I am growing older right along with the world. I guess I always saw people who were older than me as a lot older even if they were a couple years older. Mainly because I thought you had to be at a certain level or look a certain way to be their age or anywhere near it. As I write this I realize how dumb that sounds, and yet those were my exact thoughts. Age is such a crazy concept. It's probably not as complicated as I am making it out to be, but still there is just a strange feeling. Goodbye childhood hello adulthood. I guess I really should have listened to people when they told me to enjoy  my youth because it really does go by faster than you can even realize.
