How to improve or maintain skiing skills?

Big question that we hear over and over again. The answer is simple: Do harder stuff (I mean skiing), push the envelope, research conditions that are pretty disgusting, impossible snow, hard terrain and even poor visibility.

If you're young enough (below 50 or 60) you'll improve, if you are over this range, you'll maintain what you've got a little bit longer. Very simple and yes, quite difficult!
