I went from intern to PA to assistant coordinator, coordinator, production manager, assistant director then producer. But along the way, I was producing my own little shoots. I would always balance doing paid work/bigger credits but also take free work to get more experience… and it paid off.
What do you mean by “the boring stuff”… Like scheduling? Dealing with insurance?
My advice is to get out there and get a range of experience, don’t burn bridges, be positive, work really hard and treat each job like your career depends on it! When starting out, it’s good to have a flexible day job that lets you take last minute freelance work
