Because I’m a pedantic asshole: Well, classically, the only professions are medicine, law, and divinity, the rest are trades or offices.
The theme I keep seeing in your interactions is painfully clear: if hudson98 doesn’t like or approve of something then it has no value. For a man that claims not to care what people think, you spend a lot of time policing the thoughts of others.
Good luck with that
Edit: Yeah, most people would choose a different job if theirs didn’t pay enough. Being a personal trainer, on its own, won’t provide a lot of income. We can see that with any entry level job, though. In the same way a waiter can make an income to barely get by, but with experience open up their own bar or make money doing events. A smart man can start as a personal trainer, grow that into his own training gym, coaching new trainers, an online following, etc.
