It's unavoidable. You're going to give a script away to an enthusiastic producer who promises the world and then takes it all from you. Or you're going to be a camera operator for four months on the promise of a deferred payment that never comes because it wasn't on paper. Or you'll pay some charlatan from Craigslist a year's wages because of some scheme he's running that you think will make you successful.
You think you're wise, but you're not. Because everyone has this story. We're so hungry for success, that we dive in and trust people. But this industry always has and always will attract people who betray that trust. And when we begin we begin naively, and we do things because we think we'll get the credits, and we think there are shortcuts.
But you'll accidentally sign a bad script deal that you should've got a lawyer to look at. And you'll spend your money on some bullshit course that you should've got your parent's wisdom-like advice on first.
Your instincts as an individual are the key to being an artist. But artists are also dumb and naive. We sign bullshit deals. We give our rights over, we work too hard, and we let someone else pick up the rewards.
First time it happens you wanna vomit. The second time it happens you wanna quit. Eventually you just become wise, and you know how to handle yourself, and your art, and your value. You stop making the bad deal.
Everyone has this story.
