There's a great interview with actor turned screenwriter, Taylor Sheridan on YouTube. Sheridan recently brought to life the critically acclaimed stories, Sicario and more recently, Hell or High Water.

During the interview Sheridan admits he knew nothing about writing a film. Perhaps equally important, he knew how not to.
“I
have absolutely no idea how to do this but I know exactly how not to…tell
the story I want to tell, be honest…I write movies I want to
see about things that interest me," he concluded.
Not only is it crucial to know the pitfalls of creating something meaningful, but I also gathered from Sheridan's words that it's also okay to start before you feel ready.
You don't have to have it all together to do something remarkable. Just begin.
