Filmmaking is a stressful form. Waiting is the norm. No matter how enthusiastic, prepared and persistent you are, there are times where you must wait.
But, there is also another option. The DIY route; birthed from a punk rock attitude, great to relieve temporary anxiety, or, in some cases, to reign over control and defeat anxiety. To feel in charge, less frustrated and more enabled. To be what seemed denied to you in world of gatekeeping foundations.
However, the ceiling is limited in height. Not always, but more so than not. What is this ceiling? Audience, scope, professionalism, hierarchy, name talent, etc, etc. Of course, none of these matter if your art beckons you to create what you need.
In my eyes, both are valid. It's the execution of either form that matters. But, what also matters is your piece of mind. And if you can find it with no money, then do it.
But, filmmaking takes time. Lots of time. So, just know that the time you take for one thing, takes away from the other thing. And sometimes, that particular car chase you have in your mind does not lend itself to DIY.
