I'm marching along, I got confidence

I'm cooler than a pack of peppermints

And I haven't been this excited since

I can't remember when!

I'm off on this remarkable adventure

Just riding on a rainbow

What if it's all a big mistake?

What if it's more than I can take?

No, I can't think that way

Cause I know that I'm really-really-really gonna be

okay

Hey!

I'm not giving up today

There's nothing getting in my way

And if you knock-knock me over

I will get back up again

Oh

If something goes a little wrong

Well, you can go ahead and bring it on

Cause if you knock-knock me over,

I will get back up again

What does the singer probably feel when singing the song?
