One thing to remember … in the “planning ahead department” … is that by the time you finish school thousands of hopefuls more-or-less just like you will have done the same. There will be many times more applicants clutching certifications and degrees, than there will be jobs to fill.
… At least, in Hollywood and/or its UK equivalent.
Games might, by that time, be churned out by barely literate islanders in the South Pacific where they work for coconuts.
So, you’ll need to be very creative and inventive in your search, particularly looking for something besides Hollywood and “game companies” as a potential market for your work. There are plenty of possibilities, and you will distinguish yourself simply by having the creativity to think of some of them. The best job-hunting resource you can have is not the classifieds (or its internet equivalent): it is the phone book.
You will also need to be very well-trained. Forget the dream of not-finishing-high-school or not-finishing-college and being snapped up by Steven Spielberg Himself because of your Amazing Skill. By the time you finish your training, it will be a buyer’s market.
And, strange as it may seem, don’t let these words discourage you. If you want to do CG, then by all means do it and let nothing distract you. Particularly do not let illusions distract you. Most markets have more sellers than buyers, no one ever owed you anything in this world, and “to he who hustles go the spoils.” For every product ever produced, including talents as a CG artist, there is also a salesman. In your case, that will be “you.” Plan accordingly, and good luck.
P.S. Get much beter at speling…
