Replying to Plateau of Suck

So I have progressed pretty well for a while now, but it seems like I just can't get any better.. I can spin 7's 9's all that fun stuff and grind most any rail and 270 out and stuff.. but it feels like I can't progress anymore. Not cool. I wanna start corking and doing inverted/off axis spins but I don't even know where to start. I also wanna spin onto rails and get my rail skills dialed.. just seems like I have hit a plateau and can't progress any farther. Anybody else get this problem??
