As much as people don't like to admit it, you need to work very hard in order to progress. You start by setting goals. First, you pick the low hanging fruits (learning to slide properly, being mindful of your body, air awareness). Then you start choosing tricks you wish to learn. And after you master them, you move on to the next trick.
