Hi Karlo,
As a career coach, I’d say start drawing now AND do something to earn money. You could get a job that is just about money so you can show up, go home, and get paid. Or you could look for a job that would somehow support your dream of working in the game industry. That could mean working in some kind of production or for another artist. This kind of job has the possibility of giving you insight into the industry you want to work in, so you get more than a paycheck out of it. Good luck!
Best,
Laura
