Controlling others

I asked whether l could work on believing the thought “My TV series will get made” even though this depends on the thoughts and actions of others- at the networks- eg – it’s not something l can control. You said I should work on changing the belief that it’s not something I can control. However- when it comes to relationships- we talk a lot about not expecting to control others. I would like to believe my TV series will get made and have that come true but l stumble on the fact l don’t own the intellectual property- l don’t own a network- l don’t have the millions it costs… Those are facts.
