One of the things that's nice about extreme sports is it's very clear where your boundaries lie and when you've crossed the line. You need the encouragement to find them which is where i think the whole "push yourself" comes from but once you do then you know where you stand. I use to do a lot of skateboarding when i was younger and taught my boys how to skate. I would tell them, attempt to violate the laws of physics and you will be punished. A hard slam is a very clear signal that what you assumed was not the case.
