My academic records suck. What should I do?

I've been reading a lot of posts on HN lately, but reading them makes me sad and very hopeless. Almost everyone has been exposed to some kind of childhood programming and are geniuses in one way or the other. As for me, the area from where I've been brought up is still in the stone ages. Yet I happened to enroll for a CS degree a year back out of sheer curiosity and I just loved it. BUT my grades haven't been the best for sometime now, frankly academics just wears me out and if I continue in this path, my records are surely going to hold me back and hinder my future (right?). So do you guys think someone like me can land up in a decent job besides the shitty academic records?
