Cobalt London Smaug - Who I Am

You have the powers of a god
But I am just a guy
You fly high - but I'll take the stairs
You can't die - but I don't think I'll test it
You can wait - but I have no patience
You're a god - And I'm not
I know you're a god
But of what?
I have a house - but you have heaven
I play guitar - but you play the angelic harp
I drive fast - but you outrun me
I like challenges - but you're always there to compete with me
You have the powers of a god
But I am just a guy
You fly high - but I'll take the stairs
You can't die - but I don't think I'll test it
You can wait - but I have no patience
You're a god - And I'm not
