I think many students have this idealistic belief - it's only natural - that they will be different or that they have to pound the pavement for a year, then everything will fall into place, or that all they have to do is audition for a couple of things and they will get cast. It's just not like that even for established actors.
Also forget the idea of "It's who you know." No, no, no, no, no! It's who knows YOU and who will vouch for you
