like I said, its all down to experience, physical control and mental control.
There is no manual where you can follow 5 easy instructions and be able to jump down a flight of steps or flip over a car. This sport simply doesnt work like that.
On the plus side, EVERY little new thing you learn gives a real great feeling and is one of the best senses of achievement I have ever felt, no matter if its jumping up a curb, jumping down some steps or landing your first flip (just look at my youtube video of when i landed my first flip. I spent 3 mins running around screaming lol)
