haha well simply put, there is so much competition in this industry, and so many skilled people in it, that really it all comes down to who you know, that is HUGE, or the odd people will produce something that will get picked up by a major network or perhaps win some film festivals, for me i know quite a few people in the industry and have branched out connections from there, and i just put myself out there a lot, work hard at marketing myself, thats really the best that i can answer that haha but yeah id say just keep doing what you doing, producing short films, maybe film a couple pro-bono commercials or PSA's and just produce a larger portfolio for yourself and youll land with a production or crew eventually for sure, if your persistant you wont have a problem!
