But an expert in makeup could make a pretty good career for themselves, even if they didn't work in TV. It's a half a trillion dollar industry. Look at the proliferation of makeup Youtubers, some of who (admittedly a very lucky minority) make a fortune on brand deals and endorsements.
The idea that a particular degree means a guarantee of success is the sort of attitude that leads so many to fail. I know three people who did a law degree and only one ever worked in law, because she was very career focused (and had a few connections). The others almost thought that a law degree would get them a job in the legal industry by default, and it didn't work out like that (and they didn't qualify from shit unis either). Meanwhile, I've got a friend who studied film and TV, worked really hard, really applied himself, and after university carried on that attitude. He now works as a producer-director. I have another friend who did the same course and worked for a while for the BBC, but then decided to move sideways into a more comfortable office role. Based on their respective work ethic at university, their career paths don't surprise me. And talking about film and TV studies, who would have thought in 2002 that 20 years later, every company on the planet would be wanting constant professional video content. Something that was seemingly a ridiculous choice at the time has become a huge growth area. Another friend of mine studied French, transitioned to ESL teaching, and then used that linguistic knowledge to retrain as a speech therapist, who now helps people learn to speak again after a stroke. You never know where your education is going to lead, except that for most people, it's not into the field you're actually studying for.
