Excellent posting, although I am pretty certain most people who alight on these pages will simply ignore it. The truth is that of the many many people who want to work in Film and TV, only a very small proportion will make a lifetime career out of it.
And yes, you, reading this - that means you.
It doesn't matter how ambitious you are, how hardworking and determined, how capable and inspired, you may well be wasting your time at University and for several years after. It is not a meritocracy, it is not a level playing field and it is not a bed of roses if you do get any work after you graduate.
Think very very carefully before embarking on this. "Follow your dream" is often the most stupid advice to rely on.
