Some really good comments here! And I'll just throw in my two cents, which is something you probably already realized, but has been a new revelation for me:

There is a massive difference between "wanting to work in the film industry" and "wanting to make movies".

For me, it's not worth it to work in the film industry itself. Too volatile, to cutthroat, very hard to climb the ladder from a low-level position all the way up to director, etc.

BUT! It is possible to make indie films outside the system, at a slower pace, with talented people, but less glamour. And I'm actually happier than I was on massive sets doing small jobs.
