I can be an Adult....Right?

There is a mindset that you develop when you are a perpetual student. It's the mindset of well, a student. I can't escape it, it's what I do and who I am. But as I progress and get ready to end this degree in December, I realize that there has to be a change sometime. Maybe not in the literal sense but of the traditional, finish school, get a job realm, but maybe in the representative realm of, "you are an adult, time to do adult things." In a lot of ways it's easy for me to see that I have transitioned into that stage. I am not the text happy, abbreviated word, Facebook on your phone while you're driving person that I see is so common among many (definitely not all) of the youth today. Also, you could probably make the argument that this digital mindset has a good chance of lasting for the rest of their lives.
What I'm trying to get at is that, as my number gets larger, am I going to have a epiphany while doing one of my not quite adult things? Don't know. I dress like my students. Well, let's say I dress like an Alabama version, er (my shorts at least reach my knees) a student. I don't get paid much, I don't own property, I can hardly afford to take my girlfriend out. In fact she quite often has to pitch in. I live in an apartment with four people, none of whom I knew prior to moving in. To further solidify my not quite there adult status, a lot of the people I see everyday are in similar situations (not they think about this like I do). I had one colleague say that she be an adult an buy a car, the scooter wasn't cutting it.
I know that physical conditions don't determine if you are an adult or not. Recently however, they seem to be telling me that this shouldn't be this way forever. Ans I think that the best way to remedy this is by accepting the challenge of winning the adult mindset. Some people might disagree with me stating that I should try and stay in that youth mindset as long as I can. But, really, I don't want to. I feel like it's time to start getting where I want to be. But right now I'm not 100% sure I know exactly where that is. I have a good Idea of the road I'm supposed to be on, I just don't know where I'll stop.
