I know a photographer, who runs courses on how to take photos, he also sells images from a gallery. It's always funny when some of his trainees start their own business, and copy his pictures/locations/marketing strategies and become competition. Hilarious as he always feels like he's a victim and blocks them on social media and tries to talk shit about them behind their backs. Like dude you showed them how to do it.
So yes, you can, but it's more about business skills.
And you won't love photography anymore.
