Its hard when your start out again on the new season, ive only been skiing 4-5 times this year @ my local hill, (so far) Because you have all the tricks that you got last year in memory but they arnt in muscle memory yet. For me its a good 8 months off skiing before i can do it again, thats a long time to lose that. But anyways, ive had the same problem before, you just have to not worry about tricks, and pushing yourself to "get your shiit," jus go out and have fun, ski with friends, go look for pow stashes etc...when you start having fun and getting "loose" you'll get your tricks and more no problem. I actually learned a couple on the first day.
