Unsure of career switch paths

I’m in my 30s with a bachelors degree and over a decade of work experience in film post production. Sometimes I still enjoy my work but it is unpredictable and I don’t have the same passion many peers do. I often day dream of doing something different, getting higher education. I love working with seniors but I don’t think I would be successful or can afford nursing programs. I’ve considered potential administrative roles but again am unsure if it’s right for a person used to working for themselves. And would I miss more creative work which seems to be the current skill set? Im clueless and feel like time is ticking to have more than a vague desire to do something else. When you were changing careers what questions did you ask yourself? How could I be more confident in researching ideas?
