Replying to How many times did you fall on a box

...before you got it down?

I'm a really new park skiier so please don't be an asshole. Today was my first day on boxes and it was painful. I can do boxes that don't have a gap between the kicker and the box, but otherwise I got owned. I could do a full 90 onto the box but I could stay up for 3/4th of a 20 fter at the most before I slid backwards onto my ass. I fell at least 20 times onto the box. Tell me, how long does this take to learn and is it normal for me to get killed on the first day?
