I've Got a Pen

This notebook of mine is getting filled to the brim
Where the hell am I supposed to write when I reach the end
I wanna be the lever by which my whole world moves
But I've been holding myself back like I've got something left to lose
I wanted to stand out but I quit while I was ahead
And now I've permanently cut my edges to fit in this round bed
Sure there's no point left in crying when I've spilt all my milk
But I can't help feeling guilty over what that cow would think
I'm so bored
There's nothing left to do or new places I could feasibly explore
I'm stuck here
Not for lack of trying
I promise you I'm gonna be sincere
I'm scared to open that door
These walls are my shield for I have no sword
And why would I want one when I know
I've got a pen
