I'd argue that snowboarding wasn't author's "dream" to begin with. I think it's reductive and unfair to compare your "oh it would be cool to do that" with someone else's actual dream: as in, a passion they pour their life and soul into. Being great at anything takes much more than a passing "it would be neat to be able to do X."

And achieving a dream (say, competing at the Olympics) is a lot less glamorous than a casual tourist might imagine.
