Replying to Progressing with tricks

I'm at whistler for spring break, and am really trying to get in to some park skiing while im here. Today I had a nasty slip out from grinding a box and slammed my head in to the box when i fell which made me lose all my confidence with trying other features let alone grinding other boxes. Where did you guys start? I want to know where to begin and how to get up the fucking guts to try a three sixty on a side hit or something! Any help is very much appreciated. I want to progress but don't know how to get up the courage to try stuff, or know where to start. Btw There is no powder here and snow is basically all hard groomers and crud. Thanks for the help
