“Break a leg!” Is a traditional way of saying “good luck”. Though, now that we think about it, it’s probably more appropriate to the stage than to the ski field. So we’ll trust your judgement to know what’s best.
In any case, whenever you need to say: “That’s incredible!”, “So proud!”, “Way to go!”, “We hope the root canal goes really, really well.” Or “We think you are going to bust some serious chops today, despite the overwhelming pressure of the entire company being at stake”. We have something to help you say it. Perfectly.
