Riding switch is really a head game, you need to overcome the muscle memory and the "I can't do it" shit your head is telling you. You already know how to ride so you can be your own teacher but you need to overcome the mental block and muscle memory. The best advise I read in this thread was strap in and ride switch the whole day. I actually did this for a whole season at my local crap hill a long time ago, payoff was huge. Even still my brain tells me to turn around from time to time and I have to fight it.
