Readers are human, too. But now that the industry has become so fragmented, there are increasingly fewer really busy places where you can expect to find that sort of a job. But then if you're put off by remarks like that this is the wrong business for you. Everyone does it differently - and there ain't no easy way. Try everything, and don't give up.
Any experience is useful.
Nothing is ever wasted, even if it seems otherwise at the time. Well, typically, the industry in the UK isn't that impressed by Media Studies and Film Schools. They're fine as a course of academic study, but very few of them teach very much about what it's like to work in the industry. In some other countries you can't get anywhere without some sort of qualification. If you want to be an actor, on the other hand, then going to some kind of drama school, while not absolutely necessary, will probably be well worth it.
