Lots of good advice here. As someone said earlier, "Don't take it so seriously and over think it." I've been teaching two friends lately and their progress after two sessions has been impressive. One is a longboarder and the other is completely new to board sports. The best piece of advice I've given them is "really try to relax and not try to force things to happen". Relax your legs so that you can feel the smoothness of transitioning from heelside to toeside. Bend your knees comfortably and lightening your weight on your board by sucking your legs upward into your body as you're initiating those transitions. Don't ride like you're preparing to fall because this is often a self-fulfilling prophecy. Stick with it and smile & laugh a lot. It's supposed to be fun.
