The coolness glamour factor in the entertainment industry goes away when you've been a PA for 10 years. That being said, there are a lot of industries and fields where you spend like your entire 20s just treading water and suffering, and only after that when you emerge, bloodied and standing on the pile of your burned out former coworkers, do you get a crack at the lifestyle you envisioned that profession being like as a kid when you began the process of cementing yourself into this life.

As a kid I thought this included some obvious jobs, but now as an adult I realize a lot of professions are like this. Some of my doctor and lawyer friends have been dealt the worst hands of all.
