after the basics

Hey
I've been surfing since the beginning of the year and have grasped the basics of surfing pretty quickly and am now intermediate level. I can steer and move along waves a bit but only after they've broken. How do I surf along waves? Should I just go for it and get onto some big waves?
Thanks
