I just want to make a change

I know exactly what I want and who I want to be
I know exactly why I walk and talk like a machine
I'm now becoming my own self-fulfilled prophecy
Oh, oh no, oh no, oh no

One track mind, one track heart
If I fail, I'll fall apart
Maybe it is all a test
Cause I feel like I'm the worst
So I always act like I'm the best
