Part of why filmmaking seems challenging and impossible is because many of us start our career with the belief that filmmakers need a gazillion dollars, tons of experience and an address in Hollywood to make a living as a “real” filmmaker. While this was once true, the new model of movie making allows you to create and sell movies from anywhere in the world.
If you find yourself faced with filmmaking self doubt, you’re not alone. The important part is that you at least get a picture of what you want that is very specific. Then you should take time to work backwards. And who knows, maybe a decade from now we will be working on movie projects together.
