I went to college to pursue this idea.
5.5 years later, one major dropped (Engineering) and just scraping through by the skin of my teeth on my actual degree (BFA in Game & Simulation Art/Design), and living with other """like-minded individuals""", hell fucking no.
Couldn't stand my peers (the networking) and the work necessary to even get a foot in the door (the commitment) was a nightmare slog. There is always someone out there working much harder for less, and the fact that I found my contemporary students absolutely obnoxious and horrible to spend actual time around hurt things for me extremely bad.
For example, in my animation class I procrastinated just a bit too hard (my achilles heel). In order to pass the class, I had to stay awake working on the final project for literally 3 days straight at the end of the semester. I thought I was going to die I was running on fumes so hard. Yes it was my fault for not working every day, day-after-day, hour-after-hour, but I never found the work fun and never found my peers engaging from a 'strive to be better' perspective so I had so little motivation.
Plus I saw the writing on the wall in my school years that the major money-making direction of the industry-at-large was moving unstoppably in a direction I objected to, both from a taste/opinion perspective as well as a moral/philosophical perspective. (The focus on systems driven, psychological + sociological predatory game designs that are majorly predicated on having wide-net design to ensnare many "users" and in turn keep those "users" "perpetually engaged" and turned into paying "whales" as much as possible. See: Activision-Blizzard)
So trying to get into 'where the money was' seemed like a bad idea for me personally, and then working as an 'Indie' seemed like an unsustainable lifestyle (because it really is, to be honest).
I still love a variety of aspects about the medium, and I think it is by far the most compelling, most interesting artistic medium out there and is representative of the peak of human artistic design in many ways, but trying to make it into a career just thoroughly whipped the idea of actually pursuing a career in the field out of me.
If you don't like the work, don't like the people, and don't like what makes the money, then well, you probably shouldn't do it hahaha.
