I suspect you may be getting ahead of yourself by going straight to thinking about landing a paying gig. Everyone I know who ever even thought about getting into games started out by making them as a hobby. You might need a few years’ worth of that under your belt before you would have enough of a portfolio to compete for jobs.

It also gives you a chance to see how much you like it before you commit. If you don’t enjoy it enough to keep up doing it purely for fun, you might not like it enough to want to do it as a high pressure career choice.
