Yvon Chouinard, who founded the outdoor company Patagonia in the wake of his 1968 trip, had a quote in the film that I think will stick with me. He commented, "It's not an adventure until something goes wrong." As someone who doesn't like surprises and whose brain naturally forms contingency plans for every foreseeable outcome, I can learn a lot from Chouinard's take on adventure.
Check out the trailer below. The documentary is conveniently available for streaming on Netflix. I believe it came out in 2009 or 2010, but I just now got around to watching it.
