Have you ever felt like quitting? What kept you from going over the edge?

A bit of a vent post that I'd like some advice from :].

I feel like all of us here know that this isn't an industry that is easy to pursue. I specifically dream of being an editor in post production but as time goes on it just seems impossible to get any entey level roles, even in non film industries like broadcast news or commercials. All entry level positions I've heard back from are unpaid but still full time which I physically can't do if I want to survive day to day. I won't yap too much and talk about my personal struggles in detail but juggling some really tough personal things on top of doing work either for free or ridiculously cheap has made me feel so discouraged.

The only thing that's kept me going is that I know I dont have it in me to work an uncreative job. I'm currently an internship in a marketing department for a company and when I'm doing the normal uncreative marketing work I actually feel my soul draining.

I know this is probably a very common feeling but how have you coped with it? What changes did you have to make in your life?
