Sorry to burst your bubble but game designer/game programmer is one of these professions that you can't just say "hey, I know what I wanna do in life, I want to be a X. Now I'll just go to college to become that!". You can't right out of the blue suddenly decide to go to college to become a successful game designer/programmer/pianist/geologist/astronomer/graphical artist, because to have a successful career in those things you need a passion, and if you had the passion for it then whatever you want to make into a career would be your hobby to begin with.
In general, drive and passion for what you do will lead to success no matter what field you work in.
