i used to....all anything on a skateboard takes, just like anything else, is practice.
nobody can do everything at first just keep tryin til you figure it out.
watch tutorials((never helped me)) but they are helpful, watch other people do it, if your at the park and you see somebody rippin it up, ask him/her for some pointers or to show you something, im sure they would be willing to help.
best thing to do to get better is to get out there on that board.
