I can do all things

I love movies. Ever since watching Star Wars at the drive in as a child, movies have enthralled me.
I tried my hand at writing my first screenplay in 2004. It was about a coffee shop owner. Wasn't very good. Since then I've written two complete screenplays. One is science fiction. The other is set in medieval times.
I've had this idea for a movie. It is about a pregnant teen.
When I think about writing it, I get the feeling that I should not only write it, but direct it. That I should make this movie, not just sell the screenplay and see who buys it.
This is way out of my comfort zone, but after having spent the past week teaching drama: stage direction, voice, tone, characterization. etc.
I realized that I spent the week as a director. I turned 29 kids into actors and actresses. God showed me it is possible.
So when God gives me the green light to start writing the screenplay, securing financing, etc., I have this experience to look back upon and know
"I can do all things through Christ, who strengthens me." Philippians 4:13
