Little girl, and a big world

I am finding myself in such a big world
and I am nothing but still a little girl
I walk outside and see everything different
and I am experiencing a new kind of spirit
People look at me as if I was a new person
as if I was just a brand new version
of myself, adjusting to a new world of dreams
or so it seems
I am opening up my eyes
I realize I can no longer cry
I am larger then life
no time to care about the strife
I put my head up high
I no longer need to try
to get approval from others
because why should I even bother
I am great and I am strong
I am finally where I belong
Though I may still be young
I will never lose my sense of fun
because while I'm still a little girl
in this big ass world
I'm gotta live it up before its too late
so many options left in my future to create

I just recently graduated High School, and I feel myself already changing, thats why I wrote this poem. Please tell me what you think. Thank you! =)
