There is redemption in sadness. It tells me that for nearly five months in 2003, I lived life with the open, raw, refreshing outlook of the young. The payoff, though difficult to quantify, is much greater than I expected. I have no regrets about having gone -- it was the right thing to do. I think about it every day. Sometimes I can hardly believe it happened. I just quit -- and I was on a monumental trip. I didn't suffer financial ruin, my wife didn't leave me, the world didn't stop spinning. I do think of how regrettable it would have been had I ignored the pull that I felt to hike the trail. A wealth of memories could have been lost before they had even occurred if I had dismissed as a whim my inkling to hike. It is disturbing how tenuous our potential is due to our fervent defense of the comfortable norm.
