Nothing

I'm nothing, you say?
Well, I can always go away.
I can run and never look back.
I can count and never lose track.

Count the days that I've been gone.
Count the ways that took too long.
I'm running and I won't trip.
I'm talking and I won't slip.

You will hear what I have to say.
You will know that life doesn't go your way.
You're not going to slow me down.
You're not going to create a frown.
