For me there is no mental game to skiing, at least the type of skiing I do
It's like breathing (well some of you might even focus on that!)
Never an off day, just days where conditions dictate new approaches or different gear. For me that's fun. I can only think of one day in the last couple decades where I quit early. The snow had the quality of Velcro and would literally stop you in your tracks when you came through that 'zone' on the mountain. I had nuth'n in the quiver for that!
The thread has kind of gone in a different direction, but just to be clear, my original question wasn't about having an off day. Other than the day I tore my knee up and broke my leg, I don't think I've ever had a bad day skiing.
I was trying to get at, for example, if I'm standing at the top of something that is challenging to ski, perhaps where there are consequences if I fall, I'd like to be able to ski more freely and trust my body to do what it needs to do to ski the run well. In those situations, I often find my mind defaulting to more technical thoughts (make sure I stay over my downhill ski, shoulders square to the fall line, having my hands in the correct position etc.) rather than just letting go and skiing the line I've picked.
I don't often have the same sort of issue on less challenging terrain. Maybe it's just something that's a safety blanket for me when there's a little fear in the mix.
