But now I don't know how to explain that feeling of peacefulness without explaining how hard you have to work for it. It all fits together. It's not like just sitting down somewhere and watching the clouds roll by. That's different. W: Then you'll have to include that in your point. The peacefulness of cross-country skiing is the kind you earn by effort. Why leave that out? Part of your point you knew beforehand, but part you discovered as you wrote. That's common, right? M: Yeah, I guess so ... What was said before this conversation?
