I have developed a couple rules over the years. Only fortune (the grace of God) saved my butt before I developed these rules.
1) Never take a blind jump. I always skim along the edge and have a look before turning down a blind cliff or rise or what ever.
2) Always pre run the course at slow speed, even if it makes me look like a wanker, and forces me to ski very slowly with side-slipping involved, unless it's not the sort of line that permits that, in which case it's observed carefully from above and below and any other vantage point I can get to before taking it at speed.
As to getting over it, it's all about what you are used to. If you haven't been skiing a lot of steep gnarly lines lately, it takes some time in them to get used to it again.
Also if your predicted line involves a jump, just land the jump first before thinking about any turns.
You are very wise. Great advice. I don't actually stop but I do slooooow down enough to see what's ahead and then I keep going. I take every first run of a trail slooooow and only when I'm comfortable with the run and it's lines do I pick up any of kind of speed. I have only been skiing 6-7 years so only recently have been getting into steep terrain. I like your outlook.
