Pursuing Motion Graphics as a Career

I currently work as a mostly digital artist. I color storyboards, and have an illustration background. I started with Cinema 4d and recently started with After Effects, and love it. I think it is where I want my career to go, but would love user opinions on how to get there.

Obviously there is no blanket answer, my main question is, should i do some sort of certification program, teach myself, or get a masters degree? I'm frowning on the masters, as it costs a boat load of $$ and I'm not convinced the job would pay enough to make it worth it. Though it would be a blast and I would learn a lot (i'm not as design savvy as I would like to be, what I know is innate and through a BFA degree). Are there any online schools that are recommended?

Any comments/suggestinos are appreciated.
