I think that the song represents the drive we need to experience all the possibilities in life. Melanie said to Goliath " Oh you're o bigger , you're not bigger than me'. This means that Melanie is as equal as Goliath and that he's no bigger than Melanie. Melanie shows the drive by this quote "'I'm on my way somewhere" just like " Just like i know you"re got something inside of you". This is all saying that Goliath is and can be just as equal as Melanie.
