21?!

I feel so old, I'm 21
Got memories, strange times were these
My youth was kinda' short-lived indeed
My eyes opened up too fast, may be?
It all passed by as a blink of an eye
It seems, and now it feels so far, far away

21 only 21 only 21 already 21
21 only 21 only 21 Too real for some
21 only 21 only 21 I'm not an easy one
21 only 21 only 21 But I'm still eager to run

Still don't know what I'm doing,
Stuck in my youth forever
Want to live too fast, it's been my trouble
Or blessing for all I know
Every day is a taste of a fresh air
I'm gulping down, I want to live different,
To fulfill my dreams

21 only 21 only 21 already 21
21 only 21 only 21 Too real for sum
21 only 21 only 21 I'm not an easy one
21 only 21 only 21 But I'm still eager to run
