"Let out a roar"

Now is the time for roaring.
I hate this
ALmost there almost there almost there/ I keep looking out the window for train-tracks
 I am the littlest engine that could.
I am the underdog
I am the impossible
I need air/who needs air?/ AIir is for loosers
Sleep? Well its for the graduated
They have no idea the person I really am---sad for them
