The real world

I just applied for my first job as an individual with a masters degree. It would be really awesome to get this job because its a "real" job, prestigious, and is in the city that Jeff lives. However, I can't help but wonder. Could I really do this job? Am I kidding myself applying for something like this? Who knows what will come from this, but I sucked it up and applied. The worst they can say is no.
