Anyone want to asmit to a bit of envy and jealousy towards those that are able to spend + ours a week on the mountian getting paid to hone the art of skiing? Even teaching novices improves an instructors skiing. Every minute doing it makes you better when you focus on the right things. So we project some of that air of arrogance on them to some degree out of jealousy that we can't live the life as much as they do .. It least I believe I might..
I'm not sure your (implied) envy applies to everybody.
The instructors I met in the real world are usually pretty cheerful. But reading page after page of instructors complaining about their poor pay and terrible work condition here on Epic, whatever envy I might have had disappeared after day 3 of joining the forum!
Then, reading the same instructors boasting how great they are because they get to be on snow (though not neccessary actually skiing), it can't help but to sound hypocritical. That could come across as arrogance.
Personally, I haven't met any instructors in the real world that's "arrogant" in the true sense. But I did meet a few who are obssessed with instructing everyone and everywhere. That definitely come across as arrogance to many of their impromtus "student".
I just think the ski instructing appeals to certain type of personality, the same way for professional teachers. They tend to be the most helpful people one can find. But there's no denying there're plenty of times that un-solicited "help" comes at the wrong time or wrong audiance, so it appears bossy and arrogance. I've observed the same in professional teachers.
