I first learned to ski when I was about 13, on a trip with another family who were all avid skiiers. I took a single one hour lesson at Mammoth (luckily it was a solo lesson, as there were no other newcomers in that age range), and then immediately after they took me on a blue diamond at the top of the mountain. I went down those moguls mostly on my butt. But by the end of the day I was able to handle it! They gave me no choice but to keep up, and I think that's a good way to approach it. I think it helped that I was fairly young and already an avid surfer and skateboarder.
