My interpretation of this song , because we never knows what's in the mind of the writer at the moment... is that he's making a song about how we run before to learn to walk... like Tom Petty he got amazing songs and that gave him a huge popularity but he knows that Life give ups and downs... and no one knows where we will be tomorrow today you are a star and tomorrow you can be a mr. nobody ... and that will be worst than never been a star.
but is a song that you can set it to your life, maybe you are having a ggod time (drugs, parties, having your parents alive with you, the born of a son) an this should end someday the drugs will get you down, the party will end, your parents will die and even your son can die before you... so you got to understand that nothing last forever, if you are learning day after day and lives as usual enjoying the moment knowing that it wont last forever, you'll have no regrets when all of it gets over...
i'm learning to fly but i don't have wings .... we don't have the certaintly of being flying all the time (we don't have the life purchased)....we are not inmortals, not even the rocks, not even the sea...
think about it is a reflexive song.
