Did you live out in the wilderness that whole time or travel around out of a backpack? The two are obviously very different so am curious your experience. I have had friends who have backpacked along the PCT, CDT, AT, etc. and they all returned different people.
AT 2016 SOBO section hiker. Just the northern half (from Katahdin to Harper's Ferry), so I might have only came back half a different person. :) I took it pretty leisurely and stopped in at towns often, so I probably averaged about 9-10 miles per day. I'm not an outdoorsman by any stretch, but it was nice to just get away for a while. Definitely made me appreciate the small and simple conveniences of civilization that I often take for granted.
