I wonder if people from small areas in the east or midwest are more content later than those that grew up with big mountains. Those who grew up small get content with little things - a bit of powder on the side of the trail, small drop offs, etc. You look for interesting things. So expectations are low. Going to other bigger mountains, everything is a plus.
Also the weather. One gets spoiled quickly in some places that have sunshine and snow plus cold many of the days. If you're used to gray and possible liquid followed the day after by freeze, one doesn't complain if it's gray when you go to Colorado. At least there's snow and liquid isn't falling from the sky.
Going from the opposite - big mountain to living in a different area with only small hills, could be tough. Expectations of the experience are high and the smaller mt cannot meet them.
The anti-burnout mentality:
"It's my art," Shiffrin said. "It's like a puzzle or a painting or music. When I ski, it's like a song. I can hear the rhythm in my head, and when I start to ski that rhythm and I start to really link my turns together, all of a sudden there's so much flow and power that I just can't help but feel amazing. That's where the joy comes from." - Mikaela Shiffrin 2013
