Well, the movie promises that "all you have to do is dream." I'm afraid it ain't so. I mean, I do believe in the creative visualization thing, I do think you need to dream, to envision what you want to do, who you want to be...you have to imagine the world and then exist in it, but if you really want to do anything, to actualize it, to make it real, to keep a job, put on a play, be in a band, well, truthfully, "all you have to do is schlepp!"
Maybe not the best movie tag-line, but there it is...
I mean, you don't want to be a schlepp, although, that might be inevitable, it might just come with the territory, (is there a specific gene that dictates that you will be a clumsy or stupid person?!), who knows, you play with the cards you are dealt, and that means, lugging that guitar through the turnstyle, that means making the arduous, difficult journey across the city, that means standing on an el platform with the cold winter wind cutting through you waiting for a train, that means getting chilled to the bone, so you can set up and plug in and jam with your band mates for a few hours.
So you dream, and then you schlepp and well, that's what you have to do.
