Replying to So what the hell is wrong with me?

This would be my first (did a little last year) full year of park skiing, and I think I might have some serious mental issues going on right now; I always learn a trick, have it down for a few days, then fall once and then I can never do it again. Its happened for 360s, double hand drag 360s, butter 360s, 270 out both ways, 270 on, and front switch ups. I tried a while back to get my 5s, and fell a few times, then I couldn't do 3s anymore without getting off axis. When I try front switch ups, or 270 out, I find myself barely being able to slide the box. When I try to 270 on, I always end up stopping at 180, which really sucks if its on a rail or lift tower. This is really frustrating and I'm getting worried that this is something I'm going to have to deal with whenever I learn something new. So does this happen to anyone or am I just fucked up? And if so, I would love to know how you guys deal with it. Thanks NS.
