Becoming a self-taught pro - is it even possible??

[nE0n1nja]

So I'm at a pretty weird point of my life right now.. I finished 3 years of graphic design and now I work as a graphic designer in a small studio. But for the past 3 years I've been dreaming about getting a job in the video games industry. The problem is, I just realised that I just keep dreaming, and that's it. Three years have passed since I got my Wacom, and NOTHING HAS CHANGED! I just keep thinking "That day when I start to study and practice seriously", but it's been 3 years already and I'm not even good.. I don't wanna be one of them hobbyist artists with wacoms for the rest of my life, I wanna be a pro and do this for a living.

So I needed a reality check. Will I be stuck with this shitty job forever? Should I quit? What if I quit, what will I do then? I don't have money to go to another school. Should I be sitting at home all day long and teach myself? How do I even start? Even if I do get good, how will I get a job? I don't live in the US, and in my country there is basically no entertainment industry whatsoever. I talked to my parents about this, and they said I was crazy, trading a secure job position for some slilly fixation I have.

So what do you think, has anyone been in a similar position, is this just a highschool dream I've been deluding myself with all these years? I need to act, I need to act now. HELP I"M LOST!!
