I've been having your same problem. So I just started a new mental game with myself. I used to race, so I'm pretty used to doing visualization stuff, but my new thing is cue words. Like when you train your dog, train your brain. So spend time everyday thinking about a trick, like a 3. Find a word that helps you recall everything you need to do to accomplish the trick. For me for 3's it's 3. So everytime I heard the word 3, I run through it in my head, from multiple perspectives. I'm not sure if it works yet or not, but my old race coach said it might help. She also said to keep a journal and write statements like, 'I will do a 3' and other such affirmations. Even if you don't believe them, it supposedly helps. You do have to be realistic with it though. It can't be your first day on skis, and you write, 'i'm going to land a swtich cork 1440 tailgrab' or anything.
