Kinda the mentality i take to cliffs, im not much of a park skier, but it can cause problems. Sometimes when i just turn my brain off i lose focus and get sloppy, if that makes any sense. I like giving myself a countdown, once u say dropping in 10 u can't really turn back, then start reciting exactly what i want to do in my head as im coming in, then just have everything turn off in the air. I think a similarly thought process could help with park. Also, as said earlier, go skiing with friends that are better than you that will force you to try things your not comfortable with yet, makes it alot harder to puss out.
