I guess what I meant didn't come across. Of coarse all tricks build on your previous tricks and there are tricks that tend to get learned before others. But you don't want try try tricks that you can't see your self doing simply because they are in some list of what you need to learn first. If boardsliding an ollie on rail makes more sense in your head then 50-50ing a ride on (extreme example, I know) then do that. I just want to emphasize the mental aspect of progression more then some words in an AASI handbook.
For me, I'm always watching other rider's tricks, running them through my head, and if I can make sense of it there then I will probably learn that trick.
