i did 4 years of college-level video production class in high school, worked for a public access TV station as a camera operator/editor/producer, and tried making a documentary about my friend that one time. that's basically as good as film school
the real secret is that it doesn't matter what ur credentials are. you should just make stuff because it's fun. but i still like bragging about being on tv. did you know if you get the 2am slot on a tiny irrelevant station, they kind of let you do anything? it's incredible
