CNN's John Sutter spent a month in the Arctic. He says he was tired during parts of it, very tired. The journey itself is part of the growth that comes from it, but also confidence and reward for doing hard things like hiking or camping. "I think there is something that really, and it's hard to describe," writes Sutter.
Journalist and author Michael Easter talks about his book The Comfort Crisis with EconTalk host Russ Roberts. Easter thinks modern life is too easy, too comfortable. To be healthy, he says, we need to move out of our comfort zones and every once in a while try to do something, especially something physically demanding, that we didn't think was possible. Easter discusses rising levels of anxiety and depression in the West and why taking on challenges can be part of the solution.
