If you try a trick loads of times, fall, get hurt, try some more, get close then fuck up at the end it drives you insane. If you hate someone for getting angry because they've had X amount of tries, their body is one big pain and they know deep down they can make it, then you've just never felt the madness.
I try really hard never to throw my skis for fear of smashing the bindings, but I've thrown, kicked and stomped skateboards before. I'm aware its stupid but by pushing yourself really hard for that one trick, you can drive yourself crazy.
